Abstract
Several hydroxycinnamic acid derivatives, p-coumaric acid, ferulic acid, N,N'-dicoumaroylputrescine (DCP), N-p-coumaroyl-N'-feruloyl-putrescine (CFP), and N,N'-diferuloylputrescine (DFP) were isolated and purified from corn bran. To develop the skin whitening agent, we investigated the effects of hydroxycinnamic acid derivatives from corn bran, on melanogenesis. CFP and DFP inhibited melanin synthesis in a dose dependent manner up to 44.7 6.0 %, and 58.5 3.1 % at a concentration of 50 , respectively. The intracellular tyrosinase activity decreased about 42.5 14.6 %, and 9.0 4.4 % at a concentration of 50 of CFP and DFP, respectively. Our results suggest that inhibitory effects of hydroxycinnamic acid derivatives on melanogenesis are due to the inhibition of the intracellular tyrosinase activity. These results indicate that these hydroxycinnamic acid derivatives from corn bran may be potential natural skin whitening agents.
