    Abstract:

    Due to the high safety of natural extracts,it becomes hotter on cosmetic efficacy study in recent years. The active ingredient and inhibition of tyrosinase activity in vitro of Nymphaea hybrid extracts are determined,then using the cell model of B16 mouse melanoma cell to observe cell morphology and assay proliferation rate,melanin content and intracellular tyrosinase activity of the yellow and blue whole flower extracts. The results show,the extracts can inhibit tyrosinase activity in vitro. 60% ethanol extracts of yellow flower and blue flower can effectively reduce cell proliferation rate and inhibit melanin synthesis as well as intracellular tyrosinase activity. The proliferation rate for high dose group(100 μg/mL) of the two extracts are respectively 84.44%±1.77%,48.24%±3.14% and melanin content are 69.69%±1.40%,66.98%±2.44%. So it is confirmed that Nymphaea hybrid Extracts have protective whitening effect.
