摘　　要：从毛叶寄生TaxillusnigransDanser的叶中分得8种化合物，由理化性质及光谱分析鉴定，它们分别为（＋）-儿茶素〔（＋）－catechin,Ⅰ〕，7－O-没食子酰-（＋）-儿茶素〔7－O－galloyl－（＋）－catechin，Ⅱ〕，异槲皮甙（isoquercitrin，Ⅲ），广寄生甙（avicularin，Ⅳ），槲皮素-3-O－（6″-没食子酰基）-β-D-葡萄糖甙〔quercetin－3-O（6″-galloyl）-β-D-glucoside,Ⅴ〕，槲生素-3-O-（6″-没食子酰基）－β-D-半乳糖工期甙〔quercetin－3－O（6″-gal-loyl）-β-D－galactoside，Ⅵ〕，芦丁（rutin，Ⅶ），槲皮素-3-O-β-D-葡萄糖醛醒甙（qu－ercetin－3－O-β-glucuronide，Ⅷ）。From the leave of Taxillus nigrans Danser eight compounds were isolated. On the basis of physico-chemical properties and spectroscopic analysis, they were identitied as (+) catechin (Ⅰ), 7-O-galloyl (+ ) -catechin (Ⅱ), isoquercitrin (Ⅲ), avicularin (Ⅳ), querceti n-3-O- (6″-galloyl ) -β-D-glucoside (Ⅴ), quercetin-3-O- (6″-gallol ）-β- D-galactosidc (Ⅵ),rutiu (Ⅶ), and quercetin-3-O-β-D-glucuronide (Ⅷ) .All of them were found in this plant for the first time.
