摘 要 ：本文对文冠果仁油非皂化物中的甾醇部分进行了比较全面的分离、含量测定和结构鉴定。采用硝酸银-硅胶G制备薄板、二氯甲烷-石油醚作展开剂,分离效果较好。我们分离和鉴定了α-菠菜甾醇(纯度高于99.5%)、△⁷-豆甾烯醇(纯度99.5%)、△^(5.22)-豆甾醇(纯度98%)和△⁷-燕麦甾醇(纯度98%),并鉴定了微量的菜油甾醇、β-谷甾醇和胆甾醇。

Abstract:The unsaponifiable matters of the oil from Xanthoceras sorbifolia Bge are separated by TLC with silica gel G into four fractions: sterols, 4-methylsterols, triterpene alcohols and hydrocarbons. The acetates of sterols are separated by TLC with 18% silver nitrate impregnated silica gel G, using CH₂CL₂-petroleum (7:3 v/v) as developing reagents. The identification of major components is carried out by TLC, m.p.,optical rotation, GLC, IR spectrum and MS or GC-MS.It is found that Δ⁷-stigmastenol, α-spinasterol and Δ⁷-avenasterol are present in large amounts in the unsaponifiable fraction, α-spinasterol (purity 99.5%),Δ⁷-stigmastenol (purity 99.5%) Δ^5.22-stigmasterol (purity over 98%) and Δ⁷-avenasterol (purity 98%) in the sterol fraction are isolated and identified, while trace Δ⁵-sterols as campesterol, β-sitosterol and cholesterol are identified only.
