Depigmentation activity of Kakamseosiokyong-san

Objective : The aim of this study was to investigate the skin-whitening effect of Kakamseosiokyong-san Method : We investigated that the extracts of Kakamseosiokyong-san inhibit activity of tyrosinase, the enzyme which converts 3-(3,4-dihydroxyphenyl)alanine to dopachrom in the biosynthetic process of melanin. the UV absorbance of the extracts in the UV - A region and UV - B region was measured by UV scanning. the effect of extracts on cell viability and melanin production in cultured B16 mouse melanoma cells was measured, and cytoprotective effects of extracts on PC12 cells injured by hydrogen peroxide was measured by MTT assay Results: The extracts of Kakamseosiokyong-san inhibited activity of tyrosinase. The extracts not only showed inhibitory effects on melanin production in cultured B16 mouse melanoma cells, but also exhibited cytoprotective effects on PC12 cells injured by hydrogen peroxide, but did not showed an absorbance in the UV - A region and UV - B region. Conclusion: These results suggest that Kakamseosiokyong-san inhibit melanin biosynthesis which is involved in hyperpigmentation and could be used as a whitening agent for the skin.
