蒙椴树叶化学成分的研究

Study on the Extracts of Tilia mongolica Leaves and Its Chemical Constituents

目的:对蒙椴树叶的化学成分进行研究。方法:通过使用乙醇溶液对蒙椴(T.mongolica Maxim.)树叶进行连续提取,利用柱层析、薄层层析、重结晶等分析提纯技术对提取物进行分离。结果:分离鉴定了3个化合物分别为β-香树脂醇乙酸酯(β-amyrin acetate)、β-香树脂醇(β-amyrin)和β-谷甾醇(β-sitosterol)。同时利用 GC-MS 对分离所得蜡状成分进行分析,确定该混合物所含烃的种类为十五到三十六碳的14种烷烃和贝壳杉-16-烯。结论:本实验方法可靠,可用于蒙椴树叶化学成分的研究。

Objective：To analyze the chemical constituents of Tilia mongolica leaves. Method：By extracting the leaves of Tilia mongolica with ethanol, the constituents were seperated by utilizing column chromatograph, TLC, recrystallization techniques. Results： Three compounds were identified as β- amyrin acetate, β- amyrin, β- sitoost- erol. Then the wax constituents were analyzed by GC - MS. They are series of alkane and kaur - 16 -ene. Conclusion：The method is reliable, stabilize and can be applied to research the Tilia mongolica.
