To use mountain ginseng adventitious roots (MGAR), which is superior in functionality compared to ginseng, and to mass produce raw materials as a functional cosmetic material, the antioxidant and cosmeceutical activities of the extracts of MGAR at different ethanol concentrations (0, 20, 40, 60 and 80%) were compared and analyzed. At first, different ethanol concentrations were compared to determine the best solvent for the extraction of phenolic compounds from MGAR. An 80% ethanol extract with 10.07 mg of gallic acid equivalents/g sample and 0.94 mg of quercetin equivalents/g sample was the best solvent in the extraction of phenolic compounds. However, the 60% ethanol extract had the highest antioxidant activity, evident by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, Trolox equivalent antioxidant capacity (35.01 mM Trolox/g sample) and ferric reducing antioxidant power (460.94 mM $FeSO_4/g$ sample). However, the inhibitory activities of the 80% ethanol extract from the MGAR against tyrosinase and elastase were higher than those of the other extracts. The results of this study show that the extract of MGAR can be used as an easily accessible source of natural antioxidant and as a possible cosmetic ingredient in the cosmeceutical industry. However, the components responsible for the antioxidant and cosmeceutical activities of the MGAR extracts are currently unclear. Therefore, it is suggested that further studies should be carried out to isolate and identify the antioxidant and cosmeceutical components in MGAR.

Objectives : Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous inflammtion of the skin. The chestnut inner shell extracts (CI) has been used as a cosmetic material for a long time in Korea. However, the precise anti-allergy effects of CI have yet to be clearly elucidated. In this study, we attempted to evaluate the effect of CI on mast cell-mediated allergy inflammation. Methods : To find the anti-allergy and inflammatory effect of CI, we investigated the inhibitory effect of CI on the production of inflammatory mediators using by enzyme-linked immunosorbent assay in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187) stimulated-human mast cell (HMC-1). Results : In this study, we found that CI did not show cytotoxic effect at up to 10 ug/ml on HMC-1. CI inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-8 in stimulated HMC-1. Maximal rate of TNF-${\alpha}$, IL-6 and IL-8 inhibition by CI (10 ug/ml) were about 47.6%, 44.1% and 22.5% respectively. In addition, we showed that Fr.3 isolated from n-Butyl alcohol layer of CI attenuated the production of TNF-${\alpha}$, IL-6 and IL-8 in HMC-1. Conclusion : Taken together, the findings of this study provide us with a novel insight action of CI as a potential molecule for use in the treatment of allergic inflammation diseases.

To evaluate anti-atopic dermatitis effect of HRHDT, we treated HRHDT in NC/Nga mice model skin induced contact hypersensitivity. Methods : Contact hypersensitivity, a local inflammatory response of skin, was induced by spreading the back skin of NC/Nga mice with 0.4${\sim}$1% DNCB. HRHDT was prepared by dissolving 3% HRHDT in solution and treated 3 weeks on the back skin. Results : HRHDT significantly reduced TEWL and erythema by 0.4${\sim}$1% of DNCB treatment compared to control group. HRHDT also reduced IgE on serum obtained from blood of DNCB-treated mice. Conclusions : These results showed that HRHDT could be used as a pharmaceutical material with anti-atopic dermatitis effect by reducing IgE in contact, hypersensitivity atopic dermatitis NC/Nga mice model by DNCB.

In this study, Kombucha, a fermented drink by adding beneficial bacteria to green tea or black tea with sugar, was classified using column chromatography, and the presence or absence of quercetin glycoside, a type of flavonoids, was confirmed through TLC. In addition, the anti-pollution effect of protecting and improving the skin from pollution was confirmed using the fraction. Keratinocytes were treated with K-QG to confirm the cell viability, showing a survival rate of 90% or more up to a concentration of 100 ㎍/mL, and the cell viability by benzo[e]pyrene and fine dust stimulation to see the anti-pollution effect was measured. At 100 ㎍/mL, the improvement rates were about 68.79% and 50.68%, respectively. In addition, as a result of confirming the expression of AhR activated by benzo[a]pyrene through Western blot, it showed an inhibition rate of about 31.08% at 100 ㎍/mL compared to the control group. Through the results of this study, K-QG is thought to be valuable as an anti-pollution functional material, protecting and improving skin irritated from benzopyrene and fine dust.

The antioxidant and anti-inflammatory effects of active ingredients in cosmetics are very important. The effects are closely related to the prevention of skin aging. Among medicinal plants, Bletilla striata Reichenbach fil. has well-known pharmacological activity. Extracted samples were prepared using sequential fractionation of ethyl acetate, butanol, and water. The antioxidant effect of the fractions was confirmed by DPPH and ABTS+ radical scavenging. Among the various fractions of B. striata Reichenbach fil., ethyl acetate was associated with a reduction in nitric oxide production, which was induced by LPS (lipopolysaccharide) treatment in a dose-dependent manner. In addition, the production of iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2), which are upstream regulators of nitric oxide production, was also inhibited. Thus, the ethyl acetate fraction of B. striata Reichenbach fil. appears to be a potential active ingredient for use in cosmetics.

Cosmeceutical potentials of unpolished rice vinegars containing different amounts of Monascus-fermented soybean powder (soy-koji) were investigated. Four different vinegar types were prepared using 0, 10, 30, and 50% soy-koji addition. Soy-koji vinegar showed stronger cosmeceutical properties, in terms of tyrosinase and elastase inhibitory activities as well as antioxidant capacities, than unpolished rice vinegars (P<0.05). Bioactive effects of soy koji vinegar increased with increasing concentrations of total phenolics and isoflavone aglycones (P<0.05). Results indicate that unpolished rice vinegar supplemented with soy-koji can be an efficient strategy to improve bioactivities in vinegar with associated enhancement of cosmeceutical functionality.

The effects of Lactic acid bacteria have been investigated on anti-tumor. cholesterol reduction in blood. promotion of immune and skin-beauty. We are focused on cosmeceutical activity of Lactic acid bacteria (LAB). Ml, which is found in Korean traditional food. Kimchi The LAB.Ml has been identified as Lactobacillus plantarum Ml and individually cultured with Soybean soup and Soybean-Curd whey, until the total acidity has been reached the highest. After then, cell-free extracts from Ml have been used for the following studies. We assessed the effect of Lactobacillus plantarum Ml on the depigmentation of B16FlO melanoma cell. The melanin content of cells was decreased with 1-3% of cultured extracts. The tyrosinase activity was reduced by cell-free extracts of Lactobacillus plantarum Ml. Anti-aging and anti-oxidative activity of Ml cultured extract was also studied in NIH-3T3 human fibroblast cells. It showed that induction of cell proliferation. collagen synthesis and free radical scavenging activity. Additional studies for anti-fungal and anti-acne activity were also detected on Staphylococcus aureus and Propionibacterium acnes, respectively. These results suggest that cultured extract of Lactobacillun plantarum Ml would be used for cosmeceutical ingredients through multifunctional reaction on skin such as whitening, anti-wrinkle. anti-oxidation and anti-acnes.
