The Study on Depigmentation of Kamibangpungtongsung-San

Objective: This study was performed to detennine the depigmenting effects of Kamibongpungtongsung-San. Methods: To determine the depigmenting effects of Kamibangpungtongsung-San. we measured the degree of tyrosinase inhibition, melanin production & cell viability in cultured B16 melanoma cells, UV screen and cytoprotective effects on PC12 cells injured by hydrogen peroxide. Results: Komibangpungtongsung-San did not show inhibitory effects on melanin production in melanoma cells, UV screen and cytoprotective effects on PC12 cells injured by hydrogen peroxide. However it showed mild inhibitory effects on tyrosinase activity. Conclusion : This study shows that Kamibangpungtongsung-San, a generally used prescription for dermatologic diseases, do not have depigmenting effects via tyrosinase inhibition. Therefore, the depigmenting effect and mechanism of depigmentation by Kamibangpungtongsung-San need to be evaluated and investigated in other directions.
