采用硅胶柱层析、聚酰胺柱层析和Sephadex LH-20柱层析的方法，对细叶Lophatherum gracile Brongn茎叶的化学成分进行了研究。根据理化常数和光谱分析对它们的结构进行了鉴定。分离得到7个化合物，分别为：圆柱素、tricin、尿嘧啶、獐牙菜苷、7-甲氧基木犀草素-6- c -β- d -半乳糖苷、salcolin-7-O-β- d -葡萄糖苷和木犀草素-7- o -β- d -葡萄糖苷。其中尿嘧啶、盐碱-7- o -β- d -葡萄糖苷、木犀草素-7- o -β- d -葡萄糖苷为首次从该属植物中分离得到。
To study the chemical constituents from the stems and leaves of Lophatherum gracile Brongn,the compounds were isolated by column chromatography on silica gel,polyamide and Sephadex LH-20.Their struc-tures were elucidated on the basis of physicochemical constants and spectral analysis.Seven compounds were isolated and identified as cylindrin,tricin,uracil,swertiajaponin,7-methoxyluteolin-6-C-β-D-galactopyranoside,salcolin-7-O-β-D-glucopyranoside and luteolin-7-O-β-D-glucopyranoside.Of which,uracil,salcolin-7-O-β-D-glucopyranoside,luteolin-7-O-β-D-glucopyranoside were isolated from the genus Lophatherum for the first time.
