摘要/Abstract

摘要： 本文对文冠果仁油非皂化物中三萜醇部分和4-甲基甾醇部分进行一系列的分离和鉴定。三萜醇乙酸酯和4-甲基甾醇乙酸酯是采用20%硝酸银-硅胶G薄板,并用二氯甲烷-石油醚(8:2v/v)作展开剂进行分离的。效果良好。在三萜醇中,我们分离和鉴定了β-香树精乙酸酯(β-amyrinacetate纯度97%)、蒲公英赛醇乙酸酯(Taraxerol acetate纯度99.5%)、Tirucalla-7,24-dienolacetate(纯度90%)和丁酰鲸鱼醇乙酸酯(Butyrospermol acetate纯度92%)。在4-甲基甾醇中我们分离和鉴定了Cyclofontumienol acetate和4α-methylgorgostanol acetate.迄今,在文冠果仁油中尚未找到不能食用的组分。

Abstract: The unsaponifiable matters of the oil from Xanthoceras sorbifolia Bge. are separated by TLC with silica gel G into four fractions:sterols, triterpene alcohols, 4-methylsterols and hydrocarbons. The acetates of triterpene alcohols and 4-methylsterols are separated by TLC with 20% silver nitrate impregnated silica gel G, using CH₂CL₂-petroleum(8:2v/v) as developing reagents. The identification of major components is carried out by TLC, m. p., optical rotation, GLC, IR spectrum and MS. α-amyrin, taraxerol, tirucalla-7, 24-diennol and butyrospermol in the triterpene alcohol acetate fraction, cyclofontumienol and 4α-methylgorgostanol in 4-methylsterol fraction are isolated and identified. We find no evidence of the occurance of nonedibles in this oil.
