摘要: 从民间草药秃毛冬青(Ilex pubescens Hook.et Arn.uar.glaber chang)叶中分得酚性部分的结晶,已鉴定的有3,4-二羟基苯乙酮(3,4-dihydroxyacetophenone),对苯二酚(hydroquinone)莨菪亭(scopoletin),秦皮乙素(esculetin),高香草酸(homovanillic acid),vomifoliol(1～2),还有木脂素类的一新化合物为秃毛冬青甲素(Ⅰ)。本文根据红外光谱、紫外光谱、质谱、核磁共振谱和X光衍射阐明其结构。Abstract: Crystalline phenolic constituents were isolated from the leaves of Ilex pubescens Hook et Arn var glaber Chang, used as a folk medicinal herb. They were identified as 3,4-dihydroxyacetophenone, hydroquinone, scopoletin, esculetin, homovanillic acid and vomifoliol.This paper describes a new lignan compound, to be designated as glaberide Ⅰ. Its structure was ascertained through IR, UV, NMR, MS and X-ray analyses.
