Chemical constituents in aerial parts of Arachis hypogaea(Ⅲ) / 中成药

ABSTRACT

AIM:To study the chemical constituents in aerial parts of Arachis hypogea L. METHODS:Compounds were isolated and purified with silica gel and Sephadex LH-20 column chromatography,and their structures were determined by using spectroscopic analysis including MS and NMR. RESULTS:Four compounds were isolated and identified as ?-sitosterol(Ⅰ)、isomedicarpin(Ⅱ)、soyasapogenol B(Ⅲ)、daucosterol(Ⅳ). CONCLUSION:Compound Ⅱ was isolated from this plant for the first time.
