目的:研究吉祥草的化学成分。方法:对吉祥草根茎95%乙醇提取物的乙酸乙酯部位进行柱色谱分离,根据光谱数据和理化性质进行结构鉴定。结果:分离并鉴定6个化合物,分别是β-谷甾醇(1)、异万年青皂苷元(2)、胡萝卜苷(3)、(25S)-1β,3β,4β-trihydroxyspirotan-5β-yl-O-β-D-glucopyranoside(4)、奇梯皂苷元-5-O-β-D-吡喃葡萄糖苷(5)和nicotianoside B(6)。结论:化合物4、6是首次从该种植物中分离得到。 Objective: To study the chemical composition of auspicious grass. Methods: The ethyl acetate fraction of 95% ethanol extract of Ji Xing grass rhizome was separated by column chromatography and identified by spectroscopic data and physical and chemical properties. RESULTS: Six compounds were isolated and identified as β-sitosterol (1), allochondin saponin (2), daucosterol (3), (25S) -1β, 3β, 4β-trihydroxyspirotan-5β-yl-O -β-D-glucopyranoside (4), clenbuteride -5-O-β-D-glucopyranoside (5) and nicotianoside B (6). Conclusion: Compound 4,6 was isolated from this plant for the first time.
