Chemical constituents of Ginkgo Biloba L. leaves lipids

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-sitostero1, stigmasterol, ergosterol, palmitamide, glycerol tripalmtate, daucosterol, hendecane, β-caryophyllene, isophytol, nerolidol, linalool, terpineol and β-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.
