摘要
通过溶剂提取、皂化等方法制备出银杏叶类脂成分,再利用分子蒸馏以及多种色谱分离方法,结合理化性质以及波谱数据,从银杏叶类脂中共分离鉴定出15个化合物,分别为:β-谷甾醇乙酯、棕榈酸乙酯、β-谷甾醇、豆甾醇、麦角甾醇、棕榈酸酰胺、三棕榈酸甘油酯、胡萝卜苷、正十一烷、β-石竹烯、异植物醇、橙花叔醇、芳樟醇、松油醇和β-胡萝卜素。其中5个化合物:棕榈酸酰胺、三棕榈酸甘油酯、正十一烷、β-石竹烯和松油醇是首次从银杏叶中分离得到。
In this paper, lipids separated from Ginkgo biloba leaves were prepared by extraction with solvent and saponification. Fifteen known compounds were separated from Ginkgo biloba leaves by molecular distillation and chromatographic isolation. They were identified by physical and chemical properties and spectral data. The isolated compounds are β-sitosterol acetate, ethylpalmitate, β-sitosterol, stigmasterol, ergosterol, palmitamide, glycerol tripalmtate, daucosterol, hendecane, β- caryophyllene, isophytol, nerolidol, linalool, terpineol and E-carotene, respectively. The separated and identified compounds, i.e. , palmitamide, glycerol tripalmtate, hendecane, β-caryophyllene and terpineol, are reported for the first time in Ginkgo biloba leaves.
