Objective : Siegesbeckia Herba can treat various skin disease by expelling wind and removing dampness and clearing away heat and toxic material effects. This study was designed to investigate effects of Siegesbeckia Herba Extracts(SHE) on skin elasticity and whitening using B16F10 cell lines.
Method : In this experiment, We observed effect of SHE on cell viability, inhibition of melanin synthesis and inhibitory effect on tyrosinase and elastase.
Results :
1. SHE treated group showed decreased cell viability rates significantly compared with non-treated group. More than SHE 250㎍/㎖, 500㎍/㎖ and 1,000㎍/㎖ of treated groups were lower levels of melanin synthesis respectively.
2. SHE significantly showed tyrosinase inhibitory activity in vitro, SHE increased tyrosinase inhibitory activity and elastase inhibitory activity in B16F10 cells, and tyrosinase inhibitory activity in vitro.
3. Tyrosinase inhibitory activity and elastase inhibitory activity in B16F10 cells, tyrosinase inhibitory activity in vitro were not accepted statistical significance compared with non-treated group.
4. SHE treated group showed increased SOD-like activity rates significantly compared with non-treated group. More than SHE 250㎍/㎖, 500㎍/㎖ and 1,000㎍/㎖ of treated groups were lower levels of melanin synthesis respectively.
Conclusion : These results suggest that SHE can inhibit melanin synthesis and tyrosinase inhibtory activity. So, We suggest that SHE can be maintained skin whitening.
