Lotus flavoneswere used in a formula of skin cream and facial whitening effects were examined. Results shows that lotusflavones are exhibited no cytotoxicity at a concentration equal or less than 1%, and it can decrease the activityof tyrosinase at a concentration between 0.02%~0.30%. Lotus flavones can scavenge DPPH radical. The skincream containing lotus flavones declines facial melanin content. Lotus flavones have good biological safety andare suitable in cosmetics as whitening agents.展开更多
