Saposhmikoviae Radix can treat various skin disease by anti-pruitus and anti-inflammatory effects. This study was designed to investigate effects of Saposhmikoviae Radix Extracts(SRE) on skin elasticity and whitening using B16F10 cell lines. In this experiment, We observed effect of SRE on cell viability, inhibition of melanin synthesis and inhibitory effect on tyrosinase and elastase. In results, SRE treated group showed lowered proliferation rates significantly compared to non-treated group. More than SRE $125{\mu}g/m{\ell}$ of treated groups were lower levels of melanin synthesis respectively. SRE did not show inhibitory effect on tyrosinase activities in vitro and in B16F10 cells. Finally, SRE suppressed elastse type I and IV activities in dose-dependent manner in vitro. And SRE also slightly suppressed elastase activities in B16F10 cells. In conclusion, these results suggest that SRE can inhibit melanin synthesis and inhibt elastase activity. So, We suggest that SRE can be maintained skin elasticity or whitening.
