Objectives : The purpose of this study is to investigate whitening effects and anti-wrinkle effects of a few 80% ethanol extracted herbal medicines. Methods : In the first study, a few 80% ethanol extracted herbal medicines were screened for their inhibitory activities against the tyrosinase. In the second study, a few 80% ethanol extracted herbal medicines were screened for their inhibitory activities against elastase. Results : 1. We showed 28%, 27% and 19% inhibitions of mushroom tyrosinase at 500 $\mu$g/ml concentration of ASR, AIF and ABR extracts and they were showed higher anti-tyrosinase activity than arbutin's. We also could observe that the decreased mushroom tyrosinase activities in RR, CML, LR, AGR and TH extracts. 2. RR, AF and ABR (final concentrstion 1 mg/ml) were appeared 60%, 98%, 83% of inhibitions of elastase activity, and they were showed higher anti-elastase activity than that of ursolic acid. We also could observe that the decreased elastase activities in AIF, AR, LR and CML extracts. Conclusions : These results suggest that ASR, AIF and ABR extracts contribute to the anti-melanin activities and represent potential sources of whitening agent, and RR, AF and ABR extracts contribute to the anti-elastase activities and represent potential sources of anti-wrinkle agent. These results suggest that some herbal medicines could be strong potential sources of inhibition about anti-aging and whitening effects for the skin.

Objective : In this study, herbal medicine(GJE, Gardenia jasminoides Ellis; HCT, Houttuynia cordata Thunb.; CIL, Chrysanthemum indicum Linne; PMS,Paeonia moutan Sims, P. subfruticosa Makino; APL, Agrimonia pilosa Ledebour) were screened for their inhibitory activities against Tyrosinase and PMA plus A23187-induced $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells to reveal their skin -whitening and anti-allergic effect. Method : To investigate Tyrosinase inhibition we treated Mushroom Tyrosinase(Fluka, 93898) $10{\mu}{\ell}$ and 7.5mM Tyrosine (Sigma, T3754) $20{\mu}{\ell}$ with 80% ethanol medicine extracts. Then we observed 96well micro plate extinction at 490nm. In the next experiment, to investigate Anti-allergic effect we blended cultured Human Mast Cells(HMC-1) with medicine extracts. We treated the blended solution with Phorbol 12-myristate 13-acetate(PMA) and A23187, then observed $TNF-{\alpha}$, IL-6, IL-8 by ELISA (enzyme-linked immunosorbent assay) at 450nm. Results : In inhibiting Tyrosinase the results are as follows. 1. We observed 22% inhibition of Mushroom Tyrosinase at $500{\mu}g/m{\ell}$ concentration of GJE extracts. 2. We also could observe that the decreased Mushroom Tyrosinase activities in HCT, CIL extracts. In inhibiing $TNF-{\alpha}$, IL-6, IL-8 productions in HMC-1 cells the results are as follows. 1. Of the extracts examined, HCT, PMS, APL extracts showed over 50% inhibitions of Cytokines at $200{\mu}g/m{\ell}$ concentration. 2. In particular, APL extracts showed the best inhibitory effect on Cytokine productions in a dose-dependent manner. Conclusion : These results suggest that GJE extracts contributes to the anti melanin activities and represent a potential source of whitening agent. Thus these herbal medicines suggest novel drugs on anti-allergic effects.
