싸리(L. bicolor)의 생리활성물질 탐색을 위한 연구의 일환으로 비타민 C와 총 폴리페놀의 함량 그리고 각 추출물의 xanthine oxidase 및 tyrosinase 저해 활성을 측정하였다. 싸리의 비타민 C 함량은 이었으며, 싸리 생체의 총 폴리페놀은 을 함유하였으며, 싸리 추출물의 폴리페놀은 RE에서 154.95 mg/g으로 가장 높은 폴리페놀 함량을 나타내었다. 각 추출물의 농도에 따른 xanthine oxidase 저해 활성을 측

This study was intended to analyze the contents of polyphenol compounds and vitamin C, and the inhibitory activities of xanthine oxidase and tyrosinase to measure physiological efface of various extract of Lespedeza bicolor. The vitamin C content was . The content of phenolic compounds included in the flesh L bicolor was . The ethanol extract by reflux method and water extracts by the microwave-assisted method showed the highest content as 154.95 mg/g and 145.17 mg/g, respectively. The xanthine oxidase inhibitory tate of water extracts was the highest value of 87.85% at the concentration of 1,000 ug/mL. All kinds of extracts showed the highest inhibitory activity for the xanthine oxidase at the concentration of 1,000 ug/mL and a decreasing pattern of the inhibitory race over the concentration of 1,000 ug/mL. The tyrosinase inhibitory rate was increased with an increment of the extract concentrations, and the activity of ethanol extracts was the highest as 55.22% at the concentration of 3,000 ug/mL.
