Korean ginseng(Panax Ginseng C.A. Meyer) known as a oriental miracle drug is an important medicinal plant. Ginseng has been used for geriatric, tonic, stomachic, and aphrodisiac treatments for thousands years. Also, it is an antibiotic and has therapeutic properties against stress and cancer. Ginseng is widely distributed all over the world. Among them, Korean mountain ginseng has the most valuable effect on pharmaceuticals. The roots of mountain ginseng contained several kinds of ginsenosides that have many active functions for the human body. However, the study of mountain ginseng has a limit because the mountain ginseng is very expensive and rare. So, we artificially cultured mountain ginseng adventitious roots using the bioreactor culture system. We induced callus from original mountain ginseng, directly dug up in mountain and aged about one hundred ten years. Separated adventitious roots were precultured in 500ml conical flasks and then, transferred in 20L bioreactors. The adventitious roots of mountain ginseng were harvested after culturing for 40days, dried and then, extracted with several solvents. In this study, we investigated the whitening effect, anti-wrinkle effect and the safety of tissue cultured adventitious roots extract of mountain ginseng in order to identify the merit as a cosmetic ingredient. Particularly, extract of mountain ginseng adventitious roots showed whitening and anti-wrinkle effects. The inhibitory effect of this extract on the melanogenesis was examined using B-16 melanoma cell. When B-16 melanoma cells were cultured with adventitious root extract, there was a dramatically decrease in melanin contents of 8-16 melanoma cell. And we identified this extract inhibited Dopa auto-oxidation significantly. Also, when transformed mouse fibroblast L929 cells were treated with this extract, there was a significant increase in collagen synthesis. The results show significant inhibited melanization and wrinkle without inhibiting cell viability.

Citrus unshiu (C. unshiu) Markovich were dried peel of mandarin orange, of which fresh fruit was one of the famous foods in Korea and Eastern Asia. In the oriental medicine, C. unshiu peel was known to have a diuretic effect and to strengthen spleen function. Recently, natural flavonoids of C. unshiu peel have been investigated. In this study, C. unshiu peel extract containing flavonoid-glycosides was cultured with Schizophyllum commune (S. commune) mycelia producing ${\beta}$-glu- cosidase and its biological activities were investigated. ${\beta}$-glucosidase of S. commune mycelia converted the flavonoid-glycosides (rutin and hesperidin) into aglycones (naringenin and hesperetin). Fermented C. unshiu peel extract compounds were analyzed by HPLC system. The photoprotective potential of fermented C. unshiu peel extract was tested in human dermal fibroblasts (HDFs) exposed to UVA. Fermented C. unshiu peel extract extract also showed notable in vitro anti-inflammatory effect on cellular systems generating cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX) metabolites. Also, UVB-induced production of interleukin-$1{\alpha}$ in human HaCaT cells was reduced in a dose-dependent manner by treatment with fermented C. unshiu peel extract. These results suggest that fermented C. unshiu peel extract may mitigate the effects of photoaging in skin by reducing UV-induced adverse skin reaction.

We investigated the effects of aqueous extracts from twelve medical herbs on ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH)-induced melanogenesis in B16F10 mouse melanoma cell. The cells were incubated with ${\alpha}$-MSH and aqueous extracts 5 days and 2 days and then analysed melanin amount and tyrosinase activities, respectively. Nine aqueous extract of herbs examined at 1 mg/m${\ell}$ level decreased melanin synthesis in B16F10 cell, especially in Agastache rugosa, Leonurus siviricus and Murus bombycis. The significant decrease of released extracellular melanin were also observed in treated cells with aqueous extract from Leonurus siviricus, Murus bombycis and Ledebouriella seseioides. The ${\alpha}$-MSH-induced activation of tyrosinase was inhibited in cells treated with aqueous extract from Cuscutae semen, Angelica tenuissima and Agastache rugosa. These results suggest that herbs inhibiting melanogenesis through tyrosinase activity may apply to develop whitening drugs and cosmetics.

18 flowers of Compositae family were collected and extracted in aqueous methanol (MeOH). The concentrated extract was partitioned into n-hexane, ethyl acetate (EtOAc), n-BuOH, and water fractions. The extract and fractions were evaluated for total phenolics, total flavonoids, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, and tyrosinase inhibition activity. n-Hexane and EtOAc fractions of Aster yomena, n-hexane fraction of Cosmos bipinnatus White, n-hexane and EtOAc fractions of C. bipinnatus Pink showed high total phenolics. And EtOAc fractions of A. yomena, C. bipinnatus White, C. bipinnatus Red, C. morifolium Froggy, and C. morifolium Himaya exhibited high total flavonoids. EtOAc fractions of A. yomena, C. bipinnatus White, C. bipinnatus Pink, C. morifolium Yellowmable, and MeOH extract of C. morifolium Rosa significantly scavenged DPPH radical. EtOAc fractions of C. chinensis, C. bipinnatus White, C. bipinnatus Red, C. morifolium Himaya, and C. morifolium Hongsim highly inhibited the tyrosinase activity. A. yomena, C. bipinnatus White, C. bipinnatus Pink, C. bipinnatus Red and C. morifolium Himaya are evaluated as good source for whitening cosmetics materials.

In order to find new functional materials for the cosmetics application, we investigated anti-inflammatory and whitening effects of the Protaetia brevitarsis seulensis (P. brevitarsis) extracts, which were prepared by the various oriental conversion methods, as follows; fresh, roasted one time, roasted two times, roasted three times, and steamed. 2,2-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities of the various solvent extracts (80% ethanol, 50% ethanol, ethyl acetate, hexane) of P. brevitarsis extracts were 85.5, 22.4, 37.0 and 19.4% respectively. The 80% ethanol extract with the highest antioxidant activity was used for all experiments. In case of antioxidant activity test of the extracts, all the extracts showed the activities in concentration dependent manner regardless of the sample preparation methods. Superoxide dismutase-like (SOD-like) activities of the extracts roasted three times and steamed were 62.9 and 55.9%, respectively in $500{\mu}g/mL$. Effects of extracts on the inflammation of RAW 264.7 cell induced by lipopolysaccharide (LPS) showed decreasing tendency of $NO{\cdot}$ and prostaglandin $E_2$ ($PGE_2$) production; PBS fresh (38.0%), PBS roasted one time (41.0%), PBS roasted two times (69.8%), PBS roasted three times (70.1%), PBS steamed (78.5%). Intracellular tyrosinase and melanin biosynthesis inhibitory activities of the extracts were decreased in a concentration dependent manner. However, the fresh P. brevitarsis extracts without the oriental conversion method showed 90.7% decrease compared to the control group treated with ${\alpha}$-MSH alone at $500{\mu}g/mL$. Taken together, these results suggest the oriental conversion method can be applied in development of cosmetic materials in order to improve anti-inflammatory and whitening effects of the cosmetics products.

The human skin is constantly exposed to environmental irritants such as ultraviolet, smoke and chemicals. Free radicals and reactive oxygen species caused by them play critical roles in cellular damage. They not only injure the skin structure but also participate in the immensely complex inflammatory reaction. Anti-wrinkle effects of the Oriental herb extracts(OHE) were evaluated by the determination of anti-oxidation, collagenase inhibition and collagen synthesis in normal human fibroblast. OHE showed antioxidative activity as high as vitamin C, trolox and DL-penicillamine. Also OHE showed promotive effect on collagen synthesis and inhibitory effect on collagenase activity. These results demonstrated that OHE could be useful as an anti-wrinkle cosmetic ingredient.
