目的研究线叶蓟化学成分。方法采用色谱技术进行分离、纯化,通过波谱解析结合理化性质鉴定化合物结构。结果从线叶蓟中共分离得到9个化合物,分别为正十七醇(Ⅰ)、豆甾醇葡萄糖(Ⅱ)、β-谷甾醇(Ⅲ)、豆甾醇苷(Ⅳ)、乙基-β-D-吡喃果糖苷(Ⅴ)、胡萝卜苷(Ⅵ)、槲皮素(Ⅶ)、正丁基-β-D-吡喃果糖苷(Ⅷ)、KCl(Ⅸ)。结论化合物Ⅰ~Ⅸ均为首次从该植物中分离得到。 Objective To study the chemical composition of the leafhopper. Methods Chromatographic techniques were used to separate and purify the compounds. The structures of the compounds were identified by spectral analysis and physicochemical properties. Results A total of 9 compounds were isolated from the leaf spider mites. They were n-heptadecanol (I), stigmasterol glucose (II), β-sitosterol (III), stigmasterol (IV), ethyl-β-D. - Fryostatin (V), Glycosides (VI), Quercetin (VII), n-Butyl-β-D-fructopyranoside (VIII), KCl (IX). Conclusion Compounds I-IX were isolated from this plant for the first time.
