This research evaluate antioxidant and skin-whitening effect of Abeliophyllum distichum Nakai by extraction processes. First, antioxidant effects were follows: EE (70% ethanol extract) showed higher DPPH scavenging activity of 69.66% than WE (hot water exract) 59.13% at 0.3 ㎎/㎖, also UE's (70% ethanol extract by sonication process) higher than EE. Reducing power was that also EE showed higher than WE, and it was the highest value with UE's because of ultrasonic pretreatment. Next, the whitening effect tyrosinase inhibition activity was measured that EE was 23.88%, WE's was 16.69%, and UE was 23.34%. Ultrasonic pretreatment did not influence to tyrosinase inhibition activity. Cell viability showed low cell toxicity in all groups. UE's inhibited melanin synthesis, 55.1%, that is higher than EE and WE, 52.7% and 39.5%, respectively. As a result, we confirmed that antioxidant activities and skin-whitening effect by extraction process. Also, this results confirmed that the Abeliophyllum distichum Nakai extracts worth as cosmetic materials.
