Abstract

Antioxidant capacity and acetylcholinesterase (AChE) inhibitory activity of the aqueous methanolic extract of Rhus javanica were investigated in vitro. The antioxidant properties was measured by radical scavenging assays using DPPH and $ABTS^+$ radicals. The AChE inhibitory efficacy of R. javanica was tested by Ellman's assay and the total phenolic content was determined using a spectrophotometric method. All tested samples showed a dose-dependent AChE inhibitory and radical scavenging activities. In particularly, ethyl acetate (EtOAc)-soluble portion from the methanolic extract of R. javanica showed significantly higher inhibitory activity than other organic solvent soluble-portions in an AChE and radical scavenging assay systems. These results suggest that R. javanica may be possess potential benefits which might be useful in development of antioxidant and anti-alzheimer's disease ingredient.

건조 오배자를 80% MeOH로 침지 추출하여 얻어진 추출물에 대해 n-hexane, EtOAc 및n-BuOH로 순차 용매 분획하였고, 얻어진 결과물에 대하여 DPPH 및 $ABTS^+$ radical 소거능 및 AChE 저해활성을 평가하였다. DPPH 라디칼 소거능은 총 페놀성 화합물의 함량이 상대적으로 높은 EtOAc층에서 $IC_{50}$값이 $10.4{\pm}0.3mg/mL$으로 대조군인 (+)-catechin과 비교하였을 때 우수한 라디칼 소거능을 확인하였고, 오배자 추출물에 존재하는 총 페놀성 화합물의 함량과 라디칼 소거능과의 연관성을 시사하였다. 또한 $ABTS^+$ 라디칼 소거능은 EtOAc층이 $IC_{50}$값이 7.8 mg/mL 이하였고, n-BuOH층이 $IC_{50}=8.5{\pm}0.9mg/mL$으로 상대적으로 우수한 활성이 확인 되었으며, 이는 우수한 활성물질의 존재가 시사되었다. 또한, AChE 저해활성을 측정한 결과, 우수한 $ABTS^+$ 라디칼 소거능을 나타낸 EtOAc층의 $IC_{50}$은 각각 31.3 mg/mL 이하의 저해율을 나타내었으며 이는 대조군인 tacrine에 비해 다소 낮으나 분획물일 때의 활성임을 감안할 때 단일물질로 정제할 경우 더욱 우수한 효능의 화합물이 존재할 가능성을 시사하였다. 향후 이들 활성물질 동정을 통한 활성 기작에 대한 연구가 필요하며 본 연구결과는 천연물유래의 우수한 라디칼 소거능 및 AChE 저해능을 가지는 새로운 선도화합물 발굴을 위한 기초자료로 이용될 수 있을 뿐만 아니라 오배자의 식물 화학적 성분연구에 대한 기초자료로 활용가능하리라 사료된다.
