The purpose of this study was to investigate the phenolic compound compositions and skin care cosmetic physiological activities of Dioscorea japonica freeze drying yam‘s tuber, freeze drying and hot-air drying aerial bulbil extracts with MeOH solution. Total polyphenol content was higher in the yam tuber extract than aerial bulbil extract. Total flavonoid content of freeze-drying and hot airdrying aerial bulbil extract indicating higher than about 6.3 and 5.2 times content in the yam tuber extract, respectively. The major phenolic compounds of the yam tuber, freeze-drying and hot air-drying aerial bulbil extracts was p-hydroxybenzoic acid, sinapic acid and t-cinnamic acid respectively. Similarly, the flavonoids of the yam tuber, freeze-drying and hot air-drying aerial bulbil extracts were myricetin(6.02~7.43 mg%) and isorhamnetin(3.07~5.41 mg%), respectively. DPPH radical scavenging activity of freeze-drying and hot air-drying aerial bulbil extract was higher than yam tuber extracts. Tyrosinase inhibition activity of yam tuber extract indicating higher than about 32% and 22.35% freeze-drying and hot air-drying aerial bulbil extracts, respectively. The antimicrobial activities of freeze-drying yam tuber extract and hot-air drying aerial bulbil extracts was found that; E. coli KCCM 11234 and S. aureus KCCM 11593 cell growth was some inhibited at 1000 μg/ml concentration. Whereas, S. aureus KCCM 11593 cell growth was some inhibited by freeze-drying and hot-air drying aerial bulbil extracts. In addition, cytotoxicity for NIH3T3 cell line was not appeared by yam tuber, freeze drying and hot-air drying aerial bulbil extracts. These results indicated that D. japonica yam tuber and aerial bulbil extracts are functional and effective. In particular, they would be very useful as a health food and whitening cosmetic ingredients.
