【摘要】 目的研究传统藏药甘肃蚤缀的化学成分。方法利用硅胶柱色谱技术,通过理化常数和波谱分析鉴定化合物的结构。结果从甘肃蚤缀70%乙醇提取物的石油醚萃取部分分离并鉴定了脂肪类和甾体化合物共12个,分别是:棕榈酸(化合物1),棕榈酸乙酯(化合物2),二十六烷醇(化合物3),正三十烷酸(化合物4),正二十二碳酸二十六烷醇酯(化合物5),β-谷甾醇(化合物6),α-菠甾醇(化合物7),α-菠甾酮(化合物8),豆甾醇(化合物9),β-胡萝卜苷(化合物10),22,23-二氢菠甾醇(化合物11),麦角甾醇-5,8-过氧化物(化合物12)。结论化合物1～9为首次从该种植物中分离得到。更多还原

【Abstract】 Objective To study the constituents of A.kansuensis Maxim..Method The compounds were isolated and obtained by chromatographic isolation techniuqes including SiO2.A combination of physico-chemical properties and spectroscopic analysis was used to identify the structures of these constituents.Result Twelve compounds were identified as n-hexadecanoic acid(1),hexadecanoic acid ethyl ester(2),1-hexacosanol(3),n-triacontanoic acid(4),n-docosanic acid octacosanyl ester(5),β-sitosterol(6),αspinasterol(7),α-spinasterone(8),stigmasterol(9),β-daucosterol(10),22,23-dihydroxyspinasterol(11),and ergosterol-5,8-peroxide(12).Conclusion Compounds 1-9were reported in A.kansuensis Maxim.for the first time.更多还原
