사과 추출물의 미백 및 주름개선 효과

Abstract

The in-vitro whitening and anti-wrinkle effect of ethanol extracts from apple flesh and peel were investigated. The EtOAc fractions from the ethanol extracts of apple flesh and peel showed in-vitro antioxidant activities in a dose-dependent manner on ABTS radical-scavenging activity and ferric-reducing/antioxidant power, and had the highest total phenolic contents (84.25 and 318.25 mg GAE/g). In addition, the EtOAc fractions generally showed strong UV absorption within the UV-B range. In the cellular system, the melanin synthesis of the B16/F10 melanoma cells was decreased by the EtOAc fractions of apple peel in a concentration-dependent manner. The EtOAc fractions of apple peel also showed a great elastase inhibition of 46.40% at 100 μg/mL, thus showing good in-vitro anti-wrinkle characteristics. These results suggest that the EtOAc fractions from the ethanol extract of apple peel can be used as whitening and anti-wrinkle agents as well as antioxidant resources.
