Objectives : We examined three parts of Nelumbo nucifera that might be useful for skin-whitening effect. Each parts of leaves, flowers and stamen were extracted with water or 70% ethanol. Methods : This study investigated inhibitory effects of each extracts on tyrosinase activity. Extracts were tested for cytotoxicity on clone M-3 melanocyte cells, melanin inhibitory activities were further assessed. Results : The water extract of Nelumbo nucifera stamen. ethanol and water extracts of flowers exhibited inhibitory effects on tyrosinase (IC50 values 726.16, 1063, and 1732.36 ug/mL, respectively). The water extract of Nelumbo nucifera stamen, ethanol extract of flowers, both ethanol and water extracts of leaves showed relatively lower cytotoxicity, with cell viability above 80% with a concentration of 20 ${mu}g/mL$. In addition, The water extract of Nelumbo nucifera stamen inhibited the melanin production in clone M-3 melanocyte cells. Conclusions : Among each parts of Nelumbo nucifera. the water extract of stamen was the strongest candidates for skin-whitening cosmetic application.
