The promoting effect of soybean (Glicine maxim) methanol extract (GMME) on the melanogenesis and tyrosinase activity was investigated in melan-a cells, and 3-isobuty-1-methylxanthine (IBMX) was used as positive control (PC). In antioxidative ability analysis, GMME was found to contain 53.7 mg/g of polyphenol and 62.7 mg/g of flavonoid in total. Electron-donating abilities of BHT and GMME at 1,000 μg/mL were 68.4% and 14.4%, respectively. In morphological observation of melan-a cells, as the treatment concentration increased, more dendritic development and melanin accumulation observed. Melanin contents of GMME and IBMX treatment groups were significantly (p⁄0.001) higher by 51.2% and 31.6% at the concentration of 12.5 μg/mL, respectively, compared to the control group. Intra-cellular tyrosinase activities of GMME and PC treatment groups were significantly (p⁄0.001) higher by 90.0% and 54.1% at the concentration of 12.5 μg/mL, respectively, compared to the control group. Cell-extracted tyrosinase activities of GMME and PC treatment groups were higher by 12.5% (p⁄0.01) and 27.2% (p⁄0.001) at the concentration of 12.5 μg/mL,respectively, compared to the control group. GMME showed a promoting effect on melanogenesis and tyrosinase activity. From these results, it can be speculated that GMME could be applied to improve hair graying.
