摘要
本文对黄连木种子油非皂化物中的甾醇、4-甲基甾醇和三萜醇进行了研究。将甾醇、4—甲基甾醇和三萜醇分别进行乙酰化,然后,采用18％硝酸银-硅胶G薄层层析法将甾醇乙酰化物分离成个别组分;采用18％硝酸银-硅胶G离心薄层层析法将三萜醇乙酰化物分离成个别组分。利用熔点、比旋光度、气相色谱、红外光谱和质谱等鉴定其结构。甾醇部分,分离鉴定和鉴定出β-谷甾醇、胆甾醇、菜油甾醇、Δ^(5,22)-豆甾醇、Δ~5-燕麦甾醇和α-菠菜甾醇。三萜醇部分,分离鉴定了羽扇醇和β-香树精醇。4-甲基甾醇部分,鉴定了钝叶大戟甾醇和芦竹甾醇。
The unsaponifiable matters of the oil from Pistacia chinensis Bunge were separated by thin-layer chromatography centrifuge with silica gel G into four fractions: sterols , 4-methylsterols , triterpene alcohols and hydrocarbons. The acetate of sterols,4-methylsterols and triterpene alcohols were separated by thin-layer chromatography centrifuge and TLC with 18% silver nitrate impregnated silica gel G , using CH2Cl2-petroleum ether system as the developing agent. The identification of major components was carried out by TLC, mp, optical rotation, GLC, IR spectrum and MS.
It was found that β-sitosterol, △5,22-stigmasterol , △5-avenasterol, α-spinasterol , campesterol and cholesterol are present in the sterol fraction; lupeol and β-amyrin are in the triterpene alcohol fraction; and obtusifoliol and gramisterol are in the 4-methylsterol fraction.
