|
Fruits of Cornus Officinalis have been used as an astrinent, tonic and haemostatic in chinese medicine, contain a large amount of hydrolyzable tannins. The main aim of the present study was to examine the effect of Corni Fructus on melanogenesis. Cells were cultured in the presence of water extracts from Corni Fructus for 48 h, and there were estimated total melanin content as a final product and activity of tyrosinase, a key enzyme, in melanogenesis. Water extract from Corni Fructus increased the melanin content and tyrosinase activity in a dose-dependent mammer. Especially, It was observed that 100 μg/ml only water extract stimulated melanin secretion in B16/F10 melanoma cells by 130% at 48 h treatment and activity of tyrosinase increased by 160% in presence of same concentration.
