Objective: To study the effects of the extract of Angelica sinensis on the melanin synthesis in co-culture system of human melanoma and keratinocytes cells. Method: A375 and HaCaT cell were cultured respectively in MEM and co-cultured in 1∶2 ratio for 24 hours. The co-cultured cells were cultured for 48 hours after MEM containing different concentration of A. sinensis were added to the dishes. The proliferation
the tyrosinase(TYR) activity and melanin contents of the co-culture cells were measured by MTT
dopa-oxidase and NaON assays respectively. Result: Compared with control group
the cells proliferation were markedly increased by the extract of A. sinensis in the concentration range of 0.5-2 g·L-1(P<0.01)
the melanin synthesis were markedly suppressed in the concentration range of 0.25-2 g·L-1(P<0.05 or P<0.01)
TYR activity were significantly suppressed in the concentration range of 0.125-2 g·L-1(P<0.01). Conclusion: The water extract of A. sinensis can decrease the melanogenesis by decreasing the activity of tyrosinase though it can increase the proliferation of the cells in higher concentration.
