Abstract

Lycii Cordex Radicis extract (gigolpi) examined through SOS Chromotest showed a strong, dose-dependent antimutagenic effect on the tert-butyl hydroperoxide (t-BOOH) induced mutagenecity. Gigolpi revealed considerable superoxide anion radical scavenging activity under L-ascorbic $acid-CuSO_4$ system, but showed lower hydroxyl radical scavenging activity in photochemical test system. Hot-water gigolpi extract delayed protein oxidation, whereas lipid peroxidation of rat skin exposed to UVB radiation was inhibited. The results indicate that gigolpi possessing antioxidant activity against UVB-induced lipid peroxidation could be used as a raw ingredient for manufacturing functional cosmetics

본 연구는 지골피 물추출물을 이용하여 기능성 화장품을 개발하고자 생리기능(항돌연변이성, 라디칼 소거능 및 UV B 스트레스에 대한 항산화능)을 조사하였다. 지골피 물 추출물을 이용하여 tert-butyl hydroperoxide (t-BOOH)의 돌연변이원성에 대한 항돌연변이원성을, L-ascorbic acid-$CuSO_4$ 및 광화학적 시스템에서 수퍼옥사이드와 하이드록시 라디칼 소거능을 조사하였고, 비타민 E 결핍 쥐의 표피를 취하여 자외선 B조사로 산화적 스트레스를 유발시킨 뒤 지골피 물 추출물의 지방 및 단백질 산화 억제 효과를 조사하였다. SOS Chromotest에서 지골피 물 추출물은 t-BOOH의 변이원성에 대하여 강한 억제효과를 나타내었으며 억제 효과는 용량 의존적이었다. 광화학적 시스템에서 수퍼옥사이드의 라다칼 소거능은 비교적 강한 상쇄 효과를 나타내었지만 L-ascorbic acid-$CuSO_4$에서 하이드록시 라디칼 소거능은 낮았다. 자외선 B를 조사한 쥐 표피의 지질 과산화는 현저하게 억제되었으나 단백질 산화의 억제 효과는 나타나지 않았다. 이러한 결과는 UV B 방사시 지질과산화에 대해 항산화 활성을 나타낸 지골피 추출물을 기능성 화장품의 조원료로서의 사용가능성을 시사해준다.
