“…In this study, low molecular weight phenolic compounds in white ginseng were extracted using diethyl ether and ethyl acetate with medium polarity. The amount of phenolic contents, expressed as g of gallic acid equivalents per 100 g of white ginseng was 1.2 g/100 g. Hwang et al reported that the phenolic compounds in the ethyl acetate fractions of white ginseng were found to be 1.15% cinnamic acid, 0.19% p -coumaric acid and 0.24% quercetin by HPLC [17]. In general, phenolic compounds including vanillic acid, p -coumaric acid and ferulic acid have been reported to play an important role in the antioxidant activity of ginseng [9,10,11,12,13,14].…”

“…The number and size of DOPA-positive melanocytes have found to be significantly decreased in both peritoneally injected and topically applied red ginseng after the UVB radiation, suggesting that the red ginseng is an inhibitor of UVB-induced pigmentation because of its antioxidative effects [29,30]. Additionally, the numerous phenolic compounds in ginseng, such as esculetin, cinnamic acid, p-coumaric acid, quercetin, and maltol inhibit the activity of tyrosinase, which is a key enzyme of melanogenesis [9,10,12].…”
