從毛葉寄生TaxillusnigransDanser的葉中分得8種化合物，由理化性質(zhì)及光譜分析鑒定，它們分別為（+）-兒茶素〔（+）－catechin,Ⅰ〕，7－O-沒食子酰-（+）-兒茶素〔7－O－galloyl－（+）－catechin，Ⅱ〕，異槲皮甙（isoquercitrin，Ⅲ），廣寄生甙（avicularin，Ⅳ），槲皮素-3-O－（6″-沒食子?；?β-D-葡萄糖甙〔quercetin－3-O（6″-galloyl）-β-D-glucoside,Ⅴ〕，槲生素-3-O-（6″-沒食子?；?D-半乳糖工期甙〔quercetin－3－O（6″-gal-loyl）-β-D－galactoside，Ⅵ〕，蘆丁（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 Taxillns nigrans Danser eight compounds were isolated.On the basis of physico-chemical properties and spectroscopic analysis, they were identified as(+)- catechin(I)，7-O-galloyl(+)-catechin(Ⅱ)，isoquercitrin(Ⅲ)，avicularin(IV)，querce ti- n-3-O(6"-galloyl)-β-。-glucoside(V)，q uercetin-3-o。-(6"-galloyl)-β-D-galactoside(VI)， rutiu(Ⅶ)，and quercetin-3-O-β-D-glucuronide(Ⅷ).All of them were found in this plant for the first time.
