The present invention relates to a composition for skin whitening and for treating and preventing skin aging, containing an extract of grape pruning branches as an active ingredient. More specifically, the composition has shown effectiveness as a composition for skin whitening and for treating and preventing skin aging, by exhibiting antioxidative, whitening, and wrinkle-ameliorating effects through various experiments for testing antioxidative, skin whitening, and wrinkle-ameliorating effects. The antioxidative effects include: 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activities activities of inhibiting 2,2&prime-azino-bis 3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation scavenging capability measurement on hydrogen peroxide inhibiting activities and superoxide anionic radical inhibiting activities. In addition, the skin whitening effects include activities of inhibiting tyrosinase, and the wrinkle-ameliorating effects include activities of inhibiting elastase and collagenase.COPYRIGHT KIPO 2016본 발명은 포도 전정가지 추출물을 유효성분으로 함유하는 미백 및 피부노화의 치료 및 예방용 조성물에 관한 것으로, 구체적으로 DPPH 자유 라디칼 소거활성, ABTS 라디칼 양이온 소거능 저해활성, 과산화수소 저해활성 측정, 수퍼옥시드 음이온 라디칼 저해활성 등의 항산화효과 티로시나제 저해활성등의 미백활성 엘라스타제 저해활성, 콜라게나제 저해활성 등의 주름개선효과 확인 실험 등을 통하여, 항산화, 미백 및 피부주름 개선효과를 확인하여 미백 및 피부노화 치료 및 예방용 조성물로 유용함을 확인하였다.
