Background: To obtain useful cosmetic resources, this study aimed to determine the non-saponin fatty acid and inhibitory activities of collagenase and elastase by treatment of Saccharomyces cerevisiae in supercritical fluid extracted oil of the adventitious root culture of wild mountain ginseng. Methods and Results: We performed supercritical fluid extraction at various conditions such as pressure, temperature, time, and use of co-solvents, unlike the n-hexane extraction for the adventitious roots culture of wild mountain ginseng. The non-saponin-fatty acid obtained from the oil of the adventitious roots culture was incresed by treatment with S. cerevisiae. The supercritical fluid extraction was conducted using gas chromatography. Non-saponin-fatty acid content, in the oil of adventitious roots culture of wild mountain ginseng treated with S. cerevisiae for 2 days were three times higher than that in the control. In addition, the oil of the adventitious roots culture treated with S. cerevisiae was investigated for the anti-wrinkle effect by using collagenase and elastase. The oil of adventitious roots culture treated with S. cerevisiae exhibited higher collagenase and elastase inhibitory activities than those in the control. Conclusions: Supercritical fluid extracted oil of the adventitious roots culture of wild mountain ginseng treated with S. cerevisiae was found to have decreased ratio of saturated fatty acids and incresed ratio and content of unsaturated fatty acids increased. Furthermore, it showed anti-wrinkle effects in vitro.

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.

Background: Hot steaming is known to be effective in improving the biological activities of plant extracts by breaking down useful compounds to low molecular weight ones. Methods and Results: This study aimed to develop an optimal extraction and steam processing method for enhancing the low molecular ginsenoside contents of the adventitious roots culture of wild mountain ginseng. The total ginsenoside was optimally extracted when 70% EtOH was used at $50^{\circ}C$, whereas low molecule ginsenoside such as Rg2, Rh1, Rh4 and Rk1 could be extracted using 70% EtOH at $70^{\circ}C$. The adventitious roots culture of wild mountain ginseng is known to contain four major ginsenosides, i.e., Rb2, Rb1, Rg1 and Rd, however new ginsenosides Rg6, Rh4, Rg3, Rk1 and Rg5 were new abundantly obtaind after steam processing method was applied. The contents of total ginsenosides were the highest when thermal steam processing was conducted at $120^{\circ}C$ for 120 min. Unlike ginsenosides such as Rg1, Re, Rb1, Rc, Rb2, and Rh1, which decreased after steam processing, Rg3, Rk1, and Rg5 increased after thermal processing. Steam processing significanltly reduced the content of Rb1, increased that of Rg6 by about ten times than that in the adventitious roots culture of wild mountain ginseng. Conclusions: Our study showed that the optimal extraction and steam processing method increased the content of total ginsenosides and allowed the extraction of minor ginsenosides from major ones.
