Abstract

In this study, the antioxidative effect, antibacterial, inhibitory effects on tyrosinase, inhibitory effects on elastase and component analysis of Phellinus linteus (P. linteus) extracts were investigated. The ethyl acetate fraction of P. linteus extracts ($2.94\;{\mu}g/mL$) showed the highest free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity ($FSC_{50}$). Reactive oxygen species (ROS) scavenging activity ($OSC_{50}$) of P. linteus extracts on ROS generated in $Fe^{3+}$-EDTA/$H_2O_2$ system was investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction ($0.0072\;{\mu}g/mL$) showed the most prominent ROS scavenging activity. The protective effects of extract/fractions of P. linteus extracts on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The P. linteus extracts showed cellular membrane protective effects in a concentration dependent manner ($5{\sim}50\;{\mu}g/mL$). The inhibitory effect ($IC_{50}$) on tyrosinase of P. linteus extract was the highest at 50 % ethanol extract ($6.34\;{\mu}g/mL$), and the inhibitory effect ($IC_{50}$) on elastase of P. linteus was the highest at ethyl acetate fraction ($14.08\;{\mu}g/mL$). TLC, HPLC chromatogram and LC/ESI-MS of the ethyl acetate fraction obtained from P. linteus extracts were identified interfungin A (PL RPT-1a). These results indicate that extract/fractions of P. linteus can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging ROS, and protect cellular membranes against ROS. Extract/fractions of P. linteus can be applicable to new cosmeceuticals for antioxidant, antiaging, antiwrinkle and whitening.

본 연구에서는 상황버섯 추출물의 항산화 및 항노화 활성 및 항균 효과, 그리고 성분분석에 관한 연구를 수행하였다. 상황버섯 추출물의 자유 라디칼(1,1-diphenyl-2- picrylhydrazyl, DPPH) 소거활성($FSC_{50}$)은 에틸아세테이트(ethylacetate) 분획($2.94\;{\mu}g/mL$)에서 가장 큰 활성을 나타내었고, 루미놀-의존성 화학발광법을 이용한 $Fe^{3+}$-EDTA/$H_2O_2$계에서 생성된 활성산소종(reactive oxygen species, ROS)에 대한 상황버섯 추출물의 총항산화능은 추출물의 에틸아세테이트 분획($0.0072\;{\mu}g/mL$)에서 가장 큰 활성을 나타내었다. 광증감제인 rose-bengal로 증감된 사람 적혈구의 광용혈에 대한 억제 효과를 측정하였을 때 농도범위($5{\sim}50\;{\mu}g/mL$)에서 50 % 에탄올 추출물과 에틸아세테이트 분획 모두 농도 의존적으로 세포 보호 효과를 나타내었다. 타이로시네이즈의 활성 저해 효과($IC_{50}$)를 측정한 결과 50 % 에탄올 추출물($IC_{50}=6.34\;{\mu}g/mL$)에서 우수한 효과를 나타내었으며, 엘라스테이즈의 활성 저해 효과($IC_{50}$)는 에틸아세테이트분획($IC_{50}=14.08\;{\mu}g/mL$)에서 큰 효과가 나타났다. TLC, HPLC 및 LC/ESI-MS를 이용하여 상황버섯 추출물 ethylacetate 분획의 주성분을 분석하였고 hispidin 유도체인 interfungin A를 확인하였다. 이상의 결과들은 상황버섯 추출물이 ROS에 대항하여 세포막을 보호함으로써 생체계, 특히 태양 자외선에 노출된 피부에서 항산화제로써 작용할 수 있으며, 특히 상황버섯 추출물의 에틸아세테이트 분획을 항산화, 항노화 및 미백 기능성 화장품 소재로써의 응용 가능성을확인하였다.
