This study was purposed to investigate the antioxidative effects, the enzyme activity of the alcohol metabolizing and melanin production of Maesil(Prune mume). The antioxidant activity of Maesil(Prunu mume) was analyzed by measuring thiobarbituric acid reactive substances(TBARS value) and electron donating ability. And we investigated the changes of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) activity by measuring the maximum absorbency at 340nm in vitro and human study. The inhibitory effects of Maesil were investigated in vitro and in B-16mouse melanoma cells on melanin biosynthesis that is closely related to hyperpigmentation. The antioxidant activities for TBA values were 29.65% in ascorbicacid, 45.35% in BHT, 15.99% in extract of dehydrated maesil flesh(EDMF) and 25.00% in extract of dehydrated maesil juice(EDMJ). The electron donating abilities by DPPH were 96.69% in ascorbic acid, 77.82% in BHT, 34.25% in EDMF, and 42.99%in EDMJ. Electron donating abilities by DPPH in the presence of 0.02% EDMF and EDMJ were 53.21% and 59.19% respectively. Facilitating rates of ADH activity were 137.92, 131.58, 152.96, 218.70, 111.76, and 144.27% in maesil juice, 5, 10, and 15% GMT, and 0.5 and 1.0% aspartic acid, respectively. ALDH activity increased in the order of Maesil juice > ALDH > GMT > aspartic acid, and facilitating rate of ALDH activity in Maesil juice was the highest at 976.44%. Maesil extracts inhibited tyrosinase activity that converts dopa to dopachrome in the biosynthesis process. B-16 cells treated by Maesil extracts showed that the viability was over 80%. Maesil and maesil products in vitro and B-16 cells inhibited melanin production significantly.
