ABSTRACT
Objective To investigate the effect of ellagic acid on human epidermal melanocyte melanogenesis and melanin transfer, and the mechanism thereof. Methods The human melanocytes and and keratinocytes were co-cultured and purified. After passing the second generation, cells of 1∶10 ratio were inoculated into the small dish (3 cm × 3 cm). The changes of melanin content and tyrosinase activity in melanocytes were detected before and after intervention with ellagic acid (100, 10 and 1 mg/L) for 48 h. The melanin transfer in cultured cells was detected by flow cytometry method. The 10 nmol/L arbutin was used as the positive control. Results The tyrosinase activity was down-regulated by ellagic acid in a dose-dependent manner. The ellagic acid can reduce the melanin content except for the 1 mg/L of ellagic acid. The melanin transfer was also inhibited by ellagic acid in a dose-dependence manner. Conclusion Ellagic acid can be used for skin-whitening cosmetic and the depigmenting effect might be due to the down-regulation of melanogenesis and melanin transfer.
