마디풀을 80% ethanol로 침지 추출하여 얻어진 추출물에 대해 , EtOAc 및 n-BuOH로 순차 용매 분획 하였고, 얻어진 결과물에 대하여 DPPH 및 radical 소거능 및 pancreatic lipase 저해활성을 평가하였다. DPPH 라디칼 소거능은 페놀성 화합물의 함량이 상대적으로 높은 EtOAc층의 의 시험농도에서는 의 라디칼 소거능을 확인하였고, 마디풀 추출물에 존재하는 페놀성 화합물이 라디칼 소거능과의 연관성을 시사하였다

As part of our continuing search for novel bioactive natural products, antioxidant and pancreatic lipase inhibitory activities of the aqueous ethanolic extract of Polygonum aviculare were investigated. In addition, the total phenolic content was quantified by a spectrophotometric method. The antioxidant properties of the extract were evaluated by radical scavenging assays such as DPPH and radicals. The anti-obesity efficacy of P. aviculare extract was tested by porcine pancreatic lipase assay. All tested samples showed a dose-dependent pancreatic lipase inhibitory and radical scavenging activities. In terms of the value, the ethyl acetate (EtOAc) soluble portion was most potent than other solvent soluble portions. The results suggested that P. aviculare could be considered as a new potential source of natural antioxidant and anti-obesity agent for food, nutraceutical, cosmetics industries.
