TECHNICAL FIELD
The invention relates to dermatological agents containing fruit extracts and methods of using the same to treat dermatological disorders. In particular, the fruit extracts include extracts from apricots, apples, peaches, pears, pineapples, papayas, pomegranates, cherries, kiwis, tangerines, grapes, and oranges.
BACKGROUND OF THE INVENTION
The skin is the most environmentally-stressed organ in mammals, particularly in humans. Not only is the skin subjected to toxic chemicals and hostile environments, but it is also the only organ directly exposed to ultraviolet (“UV”) light in the presence of oxygen. [See, e.g., P. Mayer, et al., Cosmetic & Toiletries , 108:99-109 (February 1993)]. Lengthy exposure of the skin to UV light typically damages the skin, resulting in sunburn, photoaging and carcinogenesis.
UV light exposure in the presence of oxygen results in the creation of free radicals. In the skin, these radicals frequently trigger the release of inflammatory mediators, commonly manifested as sun burn; cytoskeletal alterations, breaking down the collagen in the skin; and may also result in structural DNA changes, such as DNA strand breaks and dimer formation. [K. Werninghaus, et al., Arch Dermatol ., 130:1257-1261 (October 1994)]. The body attempts to neutralize the free radicals generated by UV light through the use of antioxidants. Antioxidants are commonly found in two forms: enzymatic and non-enzymatic. Superoxide dismutase (SOD), catalase, and glutathione peroxidase are some of the natural enzymatic antioxidants used by the body. SOD accelerates the spontaneous reduction of superoxide free radicals into peroxides and oxygen. Catalase then further decomposes hydrogen peroxide into water and oxygen. Finally, the glutathione peroxidase reduces both hydrogen peroxide and free organic hydroperoxides. Some non-enzymatic antioxidants, such as Vitamin E (tocopherol), Vitanin A (beta-carotene), and Vitamin C (ascorbic acid) have each been individually applied to assist the skin in scavenging free radicals and neutralizing the harmful effects of UV light. [P. Pugliese, “A Brief Introduction to Free Radicals and Oxygen Stress,” Paper presented at International Conference of Aesthetics and Dermatology, Los Angeles, (February 1991)]. Conventional skin protection efforts typically attempt to either shield the skin from UV light to prevent the production of free radicals or provide additional agents capable of neutralizing the free radicals.
Topical applications are one such effort known in the art to help shield the skin from the sun's harmful UV effects. These sun-screens often are water- or oil-based lotions or ointments that incorporate photo-protectant materials such as titanium and zinc oxide. [J. Weiss, Skin , 16-23 (March/April 1996)]. Although the most widely used form of protection against exposure to sunlight, these topical applications tend to suffer from several drawbacks. First, large amounts of photo-protective materials are usually incorporated into the topical applications, some of which have recently become suspected of having toxicity or otherwise being harmful under these conditions. Furthermore, the effectiveness of such topical applications is dependent upon a constant and uniform coverage of the skin, which is often difficult to obtain. Many individuals fail to use these topical sunscreens on a regular or continuing basis, as is required under prolonged UV exposure. Finally, sunscreens and other topical applications do not consistently provide good protection for all types of UV light. [Id.].
It is also known that certain fruit extracts may be added to preparations, such as lotions, creams and gels, which are topically applied to the skin, usually for fragrance or conditioning, i.e., softening the skin.

U.S. Pat. No. 4,857,325 to Albeck et al. discloses antioxidant compositions and methods for enhancing the texture of the skin, which compositions are prepared by the water extraction of natural antioxidants from plant substrates. The plant tissues from which these water soluble antioxidants may be obtained are the leaves of spinach, clover, alfalfa, corn, tobacco, onion, garlic and algae. Other suitable plants may also be utilized if the extract of green leaves provides an antioxidant effect. The antioxidant may be used in a variety of cosmetics and is alleged to have a protective effect against ultraviolet light damage to the skin. Therefore, the antioxidant may be applied to the skin to prevent damage caused by radiation from natural sources such as the sun, or from artificial sources, either alone or in combination with other sunscreen agents.
U.S. Pat. No. 4,923,697 to Albeck et al. similarly discloses a water soluble antioxidant obtained from plants of the order Chenopodiales which has the capability of lowering the peroxide level of the skin. The antioxidant is obtained by extraction of the plant tissue with water and thereafter chromatographically separating the antioxidant component.

The compositions are allegedly useful for treating various cosmetic conditions or dermatological disorders, such as lack of adequate skin firmness, wrinkles, and dry skin.
U.S. Pat. No. 5,587,174 to Lang et al. discloses a skin and hair treatment composition that includes apple wax, as well as methods for obtaining such compositions. The apple wax is obtained by extraction of depectinized apple pomace with a variety of solvents and evaporation of the extract. The apple wax is generally disclosed to have a protective effect on the skin. Compositions according to the invention can take the form of a variety of preparations for the care or protection of skin.
U.S. Pat. No. 5,824,320 to Rouillard et al. discloses a cosmetic or pharmaceutical composition containing mangiferine, or derivatives thereof, of natural origin or obtained by chemical, enzymatic or biological synthesis, as well as compositions containing a mangiferine plant extract, in particular an Apholia or Mangifera leaf extract. Mangiferine and its derivatives, in purified form or contained in plant extracts, possess high anti-ultraviolet, anti-collagenase and anti-elastic activity. Thus, they are alleged to be particularly useful in cosmetic or pharmaceutical compositions intended for the protection of the epidermis against ultraviolet rays, for enhancing the structural quality of the skin and for providing help in combating biological and/or actinic skin aging.
U.S. Pat. No. 5,891,440 to Lansky discloses a phytoestrogen supplement prepared from pomegranate seeds and a method of preparing the supplement. The supplement can be administered orally or topically. The oral phytoestrogen supplement includes a pomegranate extract, prepared by contacting pomegranate seeds with an appropriate solvent that is non-toxic for oral use, and an aqueous extract prepared by contacting water with an herbal mixture that includes schizandra berries and Chinese asparagus root. The topical supplement includes pomegranate oil obtained from pressed pomegranate seeds and coconut milk.
U.S. Pat. No. 5,073,545 to Arima et al. discloses a method for lightening and whitening skin that comprises externally applying a composition including one or more ellagic acid compounds.
U.S. Pat. No. 5,141,741 to Ishida et al. discloses an anti-sunburn skin care composition containing a polyvalent metal salt of an ellagic acid compound and a cosmetic carrier, as well as a method of protecting human skin from sunburn by applying the composition to the human skin.
In addition, various conventional supplements have attempted to boost the body's natural antioxidant activity using vitamins, minerals, and herbs. Vitamin C, for example, is believed to reduce sun damage, and vitamin E has been used topically as an anti-inflammatory agent and for UV-ray protection of cells. Also, carotenoids may have usefulness as antioxidants, protecting against both free radicals and singlet oxygen, a highly reactive, diamagnetic excited state of dioxygen. Moreover, it is thought that minerals are typically needed to maintain the effectiveness of the body's enzymatic antioxidants. Both copper and zinc are thought to be necessary in the proper functioning of SOD. [G. La Ruche & J.-P. Cesarini, Photodermatol Photoimmunol Photomed ., 8:232-235 (1991)]. Manganese is believed to be a cofactor in the mitochondrial form of SOD. Also, selenium is thought to be necessary for glutathione peroxidase activity, one of the enzymatic antioxidants found naturally in the body. Unfortunately, few experiments into the skin-protecting effects of these antioxidants have provided scientific or conclusive results.
In particular, a study that orally administered vitamin E supplements to participants and then tested their response to the sun found that Vitamin E did not mitigate the UV damage, despite the fact that the subjects were given thirteen times the recommended daily allowance. [K. Werninghaus, et al., Arch. Dermatol ., 130:1257-1261 (October 1994)]. Furthermore, beta-carotene has been reported to have beneficial effects in some studies, but has had no effect in others. Finally, another study noted the photo-protective effect of the oral administration of butylated hydroxy toluene, but little effect was shown using vitamins C or E.
Certain herbs have also been found helpful in protecting the skin from the sun's harmful effects. Herb extracts such as burdock root, echinacea, yellow dock root and grape seeds posses detoxifying properties that have been individually applied to help the body eliminate harmful free radicals. Burdock root contains the active ingredient inulin, and is useful in treating cancerous skin conditions, as well as inflammation. Echinacoside and caffeoyl derivatives present in echinacea act as antioxidants, which protect the skin when applied topically. [R. Facino, et al., Planta Med . 61:510-514 (1995)]. Yellow dock root contains the active constituent chrysarobin, which has been used in the treatment of chronic skin diseases, such as eczema, leprosy, psoriasis, and cancer. [M. Tierra, “Planetary Herbology,” p. 194 (1988)]. Potent bioflavanoids, known as oligomeric proanthocyanidins (OPC's), are found in grape seeds. These OPC's are thought to be potent antioxidants possessing 20 times the antioxidant power of vitamin C and 50 times the antioxidant power of vitamin E. These herbs have been individually used both topically and orally to protect the skin from various afflictions.
Other studies have attempted to demonstrate the synergistic effect of a mixture of antioxidants. In one study, the subjects were given selenium and copper along with a vitamin supplement of vitamin A and E. [G. La Ruche & J. P. Cesarini, Photodermatol Photoimmunol Photomed ., 8:232-235 (1991)]. Although the supplements did protect the skin cells to some extent against ultraviolet-induced cell damage, they did not prevent light-induced erythema, i.e., redness.
Also, U.S. Pat. No. 5,290,605, discloses a soft drink that provides protection against sun damage. This drink contains a mixture of carotenoids, optionally together with vitamin C, vitamin E, or other effective antioxidants. The above antioxidants are limited to an amount which does not exceed ten vitamin ARDA equivalents of provitamin A per liter of drink.
Nutritional supplements such as Source Naturals' PYCNOGENOL® COMPLEX™ provide a variety of vitamins, minerals and herb extracts to allegedly protect the body against free radicals. In particular, the PYCNOGENOL® COMPLEX™ contains pycnogenol, proanthodyn, quercetin, Ginkgo Biloba extract, Green Tea extract, Bilberry extract, Silymarin, Tumeric extract, Hawthorn Berry extract, Rosemary extract, vitamin C (in the form of zinc and magnesium ascorbates), and magnesium.
Also, an herbal supplement and nutritional suggestions for the maintenance of the skin are disclosed in “The Scientific Validation of Herbal Medicine” by Daniel B. Mowrey, Ph. D. (p.247-251 1986). The herbal supplement consists of extracts of chaparral, dandelion root, burdock root, licorice root, echinacea, yellow dock root, kelp and cayenne. The reference also suggests the use of the following nutritional supplements: vitamin A, vitamin B 1 , vitamin B 2 , vitamin B 6 , a vitamin B complex, vitamin C, vitamin D, vitamin E, niacinamide, pantothenic acid, para-aminobenzoic acid, biotin, choline, inositol, folic acid, zinc, calcium, magnesium, and potassium.
Fruits, vegetables, and commonly used spice and herbs have also been stated to contain cancer protective factors [L. Dragsted, M. Strube, and J. C. Larsen, Pharmacology and Toxicology , v. 72, S1, pp. S116-S135 (1993)].
Although the above references disclose various supplements for the skin and studies concerning these supplements, there is no disclosure or suggestion of dermatological agents containing fruit extracts from apricots, apples, peaches, pears, pineapples, papayas, pomegranates, cherries, kiwis, tangerines, grapes, and oranges and methods of employing one or more of such fruit extracts for managing dermatological conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A dermatological agent that advantageously manages dermatological conditions has now been discovered. The dermatological agent may be used alone or in conjunction with another composition, such a sunscreen, to manage dermatological conditions. The dermatological agent includes at least one fruit extract, or a pharmaceutically acceptable salt thereof, in an amount sufficient to neutralize free radicals and a pharmaceutically acceptable carrier. The invention also includes methods of administering a therapeutically effective amount of at least one fruit extract, or pharmaceutically acceptable salt thereof, for management of dermatological conditions. The present methods and dermatological agents advantageously manage dermatological conditions, in part by providing antioxidants that are naturally present in the fruit extracts. Without wishing to be bound by theory, it is believed that these antioxidants facilitate neutralization of free radicals in the skin. In a preferred embodiment the dermatological condition is skin damage from exposure to UV light. It is believed that the antioxidants neutralize free radicals in the skin generated in part by exposure to UV light.
The terms “managing” or “management,” as used herein, include one or more of the prevention, treatment, or modification of a dermatological condition. Preferably the terms “managing” or “management,” as used herein, include one or more of treatment, or modification of a dermatological condition.
The term “dermatological conditions,” as used herein, means conditions present anywhere on the skin caused by aging or extrinsic factors such as sunlight, radiations, air pollution, wind, cold, dampness, heat, chemicals, smoke, and smoking. Dermatological conditions include, but are not limited to, dry skin; dandruff; warts; acne; keratosis; psoriasis; eczema; pruritus; age spots; reduced skin moisture; spider veins; senile purpura; lentigines; melasmas; deepening of skin lines; blotches; wrinkles; blemished skin; nodules; atrophy; rosacea; impetigo; precancerous lesions; elastotic changes characterized by leathery, course, rough, dry and yellowish skin; telangiecatic skin; hyperpigmented skin; hyperkeratotic skin; nail infections; inflammatory dermatoses; and damage to hair including, but not limited to, hair breakage, weathering damage, and thinning of hair.
In a preferred embodiment of the pharmaceutical composition, the fruit extract is present in an amount from about 0.01 to 80 weight percent, preferably from about 0.1 to 20 weight percent, and more preferably from about 0.5 to 10 weight percent. Any fruit extract capable of preventing treating or managing skin disorders and/or skin damage is suitable for use in the dermatological agents and methods of the invention. Preferably however, the fruit extract is obtained from apricots, apples, pears, peaches, pineapples, papayas, cherries, kiwis, pomegranates, tangerines, oranges, grapes, or a combination thereof. More preferably, the fruit extract is obtained from pears, peaches, pineapples, papayas, kiwis, tangerines, and oranges. Most preferably, the fruit extract is obtained from pomegranate. Pomegranate extract contains ellagic acid and other polyphenolic compounds. The fruit extract may be obtained from any part of the plant including, for example, the fruit, the skin or rind of the fruit, the seeds, the bark, the leaves, the roots, or the stem.
Any suitable pharmaceutically acceptable carrier may be used with the dermatological agents, as will be readily apparent to one of ordinary skill in the art. Pharmaceutically acceptable carriers include, but are not limited to, hydroxypropyl cellulose, starch (corn, potato, rice, wheat), pregelatinized starch, gelatin, sucrose, acacia, alginic acid, sodium alginate, guar gum, ethyl cellulose, carboxymethylcellulose sodium, carboxymethylcellulose calcium, polyvinylpyrrolidone, methylcellulose, hydroxyproply methylcellulose, microcrystalline cellulose, polyethylene glycol, powdered cellulose, glucose, croscarmellose sodium, crospovidone, polacrilin potassium, sodium starch glycolate, tragacanth, calcium carbonate, dibasic calcium phosphate, tribasic calcium phosphate, kaolin, mannitol, talc, cellulose acetate phthalate, polyethylene phthalate, shellac, titanium dioxide, carnauba wax, microcrystalline wax, calcium stearate, magnesium stearate, castor oil, mineral oil, light mineral oil, glycerin, sorbitol, mannitol, stearic acid, sodium lauryl sulfate, hydrogenated vegetable oil (e.g., peanut, cottonseed, sunflower, sesame, olive, corn, soybean), zinc stearate, ethyl oleate, ethyl laurate, agar, calcium silicate, magnesium silicate, silicon dioxide, colloidal silicon dioxide, calcium chloride, calcium sulfate, silica gel, castor oil, diethyl phthalate, glyercin, mono- and di-acetylated monoglycerides, propylene glycol, triacetin, alamic acid, aluminum monostearate, bentonite, bentonite magma, carbomer 934, carboxymethylcellulose sodium 12, carrageenan, hydroxyethyl cellulose, magnesium aluminum silicate, pectin, polyvinyl alcohol, povidine, sodium alginate, tragacanth, xanthan gum, and silicones. For example, preferred topical formulations of the pharmaceutical composition may include a silicon-containing carrier, preferably a silicone, but in amounts insufficient to cause substantial irritation. Suitable silicones include cyclomethicone or a mixture of cyclopentasiloxane and dimethicone/vinyldimethicone crosspolymer.
The pharmaceutical composition preferably includes one or more moisturizing agents. “Moisturizing agent,” as used herein, is used to include any agent that facilitates hydration of the skin by inhibiting or preventing loss of water from the skin, absorbs water from the atmosphere and hydrates the skin, or enhances the skin's own ability to absorb water directly from the atmosphere, or a combination thereof. Moisturizing agents generally minimize or prevent the skin from drying and cracking. Cracked skin is more susceptible to environmental factors that generate free radicals, which is believed to cause further damage to the skin. Thus, moisturizing or facilitating moisturizing skin reduces damage from free radicals and can help manage many dermatological conditions. Suitable moisturizing agents include, but are not limited to, acidic components, hydrophobic agents, and hydrophilic agents, or combinations thereof. Moisturizers, when used, are typically present in an amount from about 0.01 to 20 weight percent, preferably about 0.05 to 10 weight percent, more preferably from about 0.1 to 1 weight percent of the composition.

The dermatological agents of the present invention are useful for managing dermatological conditions caused by aging or extrinsic factors including, but not limited to sunlight, radiations, air pollution, wind, cold, dampness, heat, chemicals, smoke, and smoking. The dermatological agents are useful in managing dry skin; dandruff; warts; acne; keratosis; psoriasis; eczema; pruritus; age spots; reduced skin moisture; spider veins; senile purpura; lentigines; melasmas; deepening of skin lines; blotches; wrinkles; blemished skin; nodules; atrophy; rosacea; impetigo; precancerous lesions; elastotic changes characterized by leathery, course, rough, dry and yellowish skin; telangiecatic skin; hyperpigmented skin; hyperkeratotic skin; nail infections; inflammatory dermatoses; damage to hair including, but not limited to, hair breakage, weathering damage, and thinning of hair; and the like. Preferred conditions for treatment include photodamage, precancerous lesions, wrinkles, and leathery skin. In one embodiment, the dermatological agents are used to prevent, treat, or manage damage caused by exposure to sunlight. The dermatological agents are administered to a patient in need of such treatmentor such protection or management in a therapeutically effective amount so as to increase the sun protection factor of the skin.
The phrase “therapeutically effective amount” means the amount of the dermatological agent that provides a therapeutic benefit in the management of a dermatological condition. It should be understood by one of ordinary skill in the art that this amount will vary depending on the condition being treated and the patient and will be readily determinable.
The magnitude of a prophylactic or therapeutic dose of the dermatological agent in the managing a dermatological condition will vary with the sensitivity of the person's skin and the route of administration. The dose, and perhaps the dose frequency, will also vary according to the age, body weight, and response of the individual patient. In general, the total daily dose range, for the conditions described herein, is from about 1 mg to about 2,000 mg administered in about one to ten doses, preferably two to eight doses. The preferred oral daily dose range should be from about 1 mg to 2,000 mg, more preferably from about 400 mg to 1,600 mg, and most preferably from about 800 mg to 1,200 mg. In general, a preferred topical daily dosage range, in single or divided doses, should be from about 1 mg to 20,000 mg, more preferably from about 2,000 mg to 16,000 mg, and most preferably from about 6,000 mg to 10,000 mg of the compositions.
It is further recommended that children, patients aged over 65 years, and those with impaired renal or hepatic function initially receive low doses, and that they then be titrated based on individual response(s) or blood level(s). It may be necessary to use dosages outside these ranges in some cases, as will be apparent to those of ordinary skill in the art. Further, it is noted that the clinician or treating physician will know how and when to interrupt, adjust, or terminate therapy in conjunction with individual patient's response.
Although any suitable route of administration may be employed for providing the patient with an effective dosage of the dermatological agent according to the methods of the present invention, topical and oral administration are preferred. It should be understood that differing routes of administration may be used for the dermatological agent and the additional dermatological agent, sunscreen, sunblock, moisturizing agent, and the like. For example, the dermatological agent can be orally administered while the sunscreen is topically administered. Suitable routes include, for example, oral, rectal, parenteral, intravenous, topical, transdermal, subcutaneous, intramuscular, and similar forms of administration may also be employed. Suitable dosage forms include tablets, troches, dispersions, suspensions, solutions, aerosols, sponges, cotton applicators, capsules, patches, suppositories, and the like.
The dermatological agents used in the methods of the present invention include the active ingredients described above, and may also contain pharmaceutically acceptable carriers, excipients and the like, and optionally, other therapeutic ingredients. The dermatological agents herein may also be administered in conjunction, i.e., concurrently or sequentially, with other skin-protective pharmaceutical compositions or devices, such as a hat, umbrella, or the like.
Dermatological agents for use in the methods of the present invention suitable for oral administration include compositions, such as suspensions, solutions, elixirs, and aerosols; and may include carriers, such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like. In the case of oral solid preparations (such as powders, capsules, and tablets), the oral solid preparations are typically preferred over the oral liquid preparations.
Dermatological agents for use in the methods of the present invention suitable for topical administration may be presented as discrete units including aerosol sprays, each containing a predetermined amount of the active ingredient, as a powder, stick, or granules, as creams (e.g., a conditioner), pastes, gels, lotions (e.g., a sunscreen), syrups, or ointments, on sponges or cotton applicators, or as a solution or a suspension in an aqueous liquid, a non-aqueous liquid, an oil-in-water emulsion, or a water-in-oil liquid emulsion. Similarly, because of its ease of administration, a cream, lotion, or ointment represents the most advantageous topical dosage unit form.
Dermatological agents for use in the methods of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets, or tablets, or aerosol sprays, each containing a predetermined amount of the active ingredient, as a powder or granules, as creams, pastes, gels, or ointments, or as a solution or a suspension in an aqueous liquid, a non-aqueous liquid, an oil-in-water emulsion, or a water-in-oil liquid emulsion.
All such dermatological agents may be prepared by any of the methods of a pharmacy, but all methods include the step of bringing into association the carrier(s) with the active ingredient, which constitutes one or more necessary ingredients. In general, the dermatological agents are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product into the desired presentation.
For example, a tablet may be prepared by compressing or molding, optionally, with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent. Molded tablets may be made by molding, in a suitable machine, a mixture of the powdered compound moistened with an inert liquid diluent. Desirably, each tablet, cachet or capsule contains from about 1 mg to 2,000 mg of the active ingredient.
Other suitable dosage forms include tablets, troches, capsules, patches, gel caps, magmas, lozenges, plasters, discs, suppositories, nasal or oral sprays, and the like. When an oral dosage unit form is used instead of a topical dosage form, tablets, capsules, and gel caps are preferred, in which case solid pharmaceutical carriers may be employed. If desired, tablets may be coated by standard aqueous or non-aqueous techniques.
In addition to the common dosage forms set out above, the dermatological agents for use in the methods of the present invention may also be administered by controlled release means and/or delivery devices, such as those described in U.S. Pat. Nos.: 3,845,770; 3,916,899; 3,536,809; 3,598,123; 4,008,719; 5,674,533; 5,059,595; 5,591,767; 5,120,548; 5,073,543; 5,639,476; 5,354,556; and 5,733,566 the disclosures of which are incorporated herein by express reference thereto.

Testing Compositions Prepared According to the Invention
Mixed fruit capsules of Example 12 and Pom Fruit™ pomegranate capsules (containing 15 mg of pomegranate extract) of Example 13 were prepared according to the present invention. The capsules were administered to 32 human subjects to evaluate the increase in sun protection factor (SPF) value of four conventional sunscreen formulations following daily ingestion of the capsules for a period of one week. Either one or two capsules were ingested per day. The four sunscreen formulations were conventional formulations of an SPF-4 lotion, an SPF-4 lotion with antioxidants, an SPF-8 lotion, and an SPF-8 lotion with antioxidants. Subjects were healthy male or female volunteers; between 18 and 60 years of age; dependable and capable of following directions; completed a medical history form; and had read, signed, and understood an Informed Consent Form. All subjects were fair skinned with skin types I-III as determined by the following guidelines:
I Always burns easily, never tans (sensitive).
II Always burns easily, tans minimally (sensitive).
III Burns moderately, tans gradually (normal).
IV Burns minimally, always tans well (normal).
V Rarely burns, tans profusely (insensitive).
VI Never burns, deeply pigmented (insensitive).
Subjects were excluded if they had a history of abnormal response to sunlight or taking medication that might produce an abnormal response to sunlight, used alcohol in excess, exhibited current sunburn, suntan, or uneven skin tone that might be confused with a reaction from the test material or that might interfere with evaluation of test results, were pregnant or lactating females, had a known allergy to any of the components of the test articles (i.e., fruits or fruit-derived vitamin supplements), regularly used UVA sunbeds, or exhibited any visible skin disease that could be considered to affect the purpose or integrity of the study.
The following test procedure was followed:
On day 1, the Minimal Erythemal Dose (MED) was determined for each subject. The MED is defined as the time interval or dosage of UV light irradiation sufficient to produce a minimal, perceptible erythema on designated test sites. Prior to the testing phase, the MED of the unprotected skin of each subject was determined by a progressive sequence of timed UV light exposures, graduated incrementally by 25% over that of the previous exposure. The irradiation procedure was based on the method outlined in the Food and Drug Administration monograph of proposed rules for sunscreen testing published in the Federal Register, Vol. 43, No. 166, Aug. 25, 1978. A 150 W Xenon Arc Solar Simulator (commercially available from Solar Light Company of Philadelphia, Pa.) was used as the source of ultraviolet light. A continuous emission spectrum in the UV-B range (290-320 nm) was produced during the testing procedure.
On day 2, sixteen to twenty-four hours after irradiation, the sites were evaluated for erythema according to the following scoring system:
0=Negative, no visible reaction
0.5=Minimal erythema
1.0=Defined erythema
2.0=Moderate erythema
3.0=Severe erythema
After grading of the MED, four (4) 5×10 cm test areas were outlined with a surgical marking pen on the subject's back between the scapulae and the beltline, lateral to the midline. These areas were designated as areas 1-4, with an additional area designated for a concurrent MED determination (unprotected control). A 2 mg/cm 2 portion of each sunscreen formulation was applied to the appropriate designated test site and spread evenly over the site using a fingercot. The sunscreen formulation that was applied to each site on each subject was determined according to a randomization table. Irradiation of the sites was begun no less than 15 minutes and no longer than 30 minutes after application. The test areas were subdivided into sites, which were used for defined serial UV light exposures. Exposure times were selected for each site in treated areas based upon the previously determined MED of unprotected skin and the expected SPF of the sunscreen formulation.
On day 3, all test sites were evaluated approximately 16 to 24 hours after irradiation to determine minimal erythemal response. After evaluation of the test sites, each subject was instructed to ingest their assigned capsule.
On days 4-9, subjects returned to the clinic to ingest their assigned capsule. All dosing of the capsules was performed under supervision at the clinic.
On day 10, four (4) 5×10 cm test areas were outlined with a surgical marking pen on the subject's back between the scapulae and the beltline, lateral to the midline. These areas were designated as areas 1-4, with an additional area designated for a concurrent MED determination (unprotected control). The application and irradiation procedure performed on Day 2 was repeated as described above.
On day 11, all test sites were evaluated approximately 16 to 24 hours after irradiation to determine minimal erythemal response.
No adverse dermal effects were observed on the treated area of any subject. The pre- and post-ingestion SPF values were then determined for each sunscreen formulation. The SPF is defined as the ratio of the amount of energy or time required to produce an MED on protected skin (treated with sunscreen formulation) to the amount of energy or time needed to produce an MED on untreated skin. The SPF is calculated as follows:
SPF=MED Sunscreen Formulation/MED Unprotected Control
Results are based on eight (8) subjects per test condition, total of thirty-two (32) subjects. Pre- and post-ingestion mean SPF values for each sunscreen formulation and the percent change between the pre-ingestion mean SPF values and the post-ingestion mean SPF values were determined. The t-Test (Dependent) was used to determine if the pre-ingestion mean SPF values of the sunscreen formulations were significantly different than the post-ingestion mean SPF values of the sunscreen formulations. Significance was observed if P≦0.050. The pre- and post-ingestion mean SPF values for each sunscreen formulation and the percent change from pre-ingestion mean SPF values are reported in Tables I-IV.

The results of the study show that the post SPF values for SPF-4 lotion and SPF-4 lotion with antioxidants were significantly increased compared to pre-treatment SPF values after ingesting the mixed fruit capsule for one week at a dose of two capsules per day. The results also show that the post SPF values for SPF-4 lotion with antioxidants and the SPF-8 lotion were significantly increased compared to pre-treatment SPF values after ingesting the pomegranate capsule for one week at a dose of one capsule per day. Also, the post SPF values for SPF-4 lotion were significantly increased at the 92.2% confidence limit compared to pre-treatment SPF values after ingesting the pomegranate capsule for one week at a dose of one capsule per day. The results also show that the post SPF values for SPF-4 lotion, SPF-4 lotion with antioxidants, SPF-8 lotion, and SPF-8 lotion with antioxidants were increased compared to pre-treatment SPF values after ingesting the pomegranate capsule for one week at a dose of two capsule per day, these increases, however, were not statistically significant.
