摘要: 目的 研究中药白及的化学成分。方法 用多种层析方法分离白及甲醇提取物,根据理化性质和光谱数据分析鉴定化合物的结构。结果 分离并鉴定4个化合物,分别是β-谷甾醇(β-sitosterol)(1);胡萝卜苷(dancosterol(2);丁香树脂酚(syringaresinol)(3);咖啡酸(caffeicacid)(4)。 结论 化合物 2,3是首次从该植物中分离得到。Abstract: OBJECTIVE To study the chemical constituents of Bletilla striata(Thunb.) Reichb.f.METHODS The constituents were separated and purified by column chromatography with silica gel,and sephadex LH-20,and identified by spectrum,and physical data.RESULTS Four compounds were identified as:β-sitosterol(1),dancosterol (2),syrindaresinol(3),caffeic acid(4),CONCLUSIONS Compounds 2,3,were isolated from this plant for the first time.
