青钱柳化学成分的研究

Chemical constituents of Cyclocarya Paliums

目的:对青钱柳(Cyclocarya Paliums)叶进行化学成分分离研究。方法:采用硅胶柱层析、薄层层析和Sephadex LH-20凝胶层析,并通过波谱学方法鉴定化合物的结构。结果:从青钱柳叶的75%乙醇提取物的氯仿提取物中分离得到6个化合物,分别鉴定为:β-谷甾醇(β-Sitosterol)(1),山俞酸(Behenic acid)(2),3β,20-二羟基-5β-孕甾烷(3β,20-di-hydroxyl-5β-Pregnanes)(3),山奈酚(Kaempferol)(4),β-香树脂醇(β-amyrin)(5)和β-香树脂酮(β-amyrone)(6)。结论:化合物3、5和6为首次从该植物中分离得到。

AIM： To study the chemical constituents of the leaves of Cyclocarya Paliums （Batal.） Iljinskaja. METHODS： Chemical constituents were separated through chromatographic methods and their structures were elucidated by spectral analysis. RESULTS： Six compounds were isolated from the chloroform fraction through 75% alcohol extraction from the leaves of Cyclocarya Paliums. Their structures were elucidated as β-Sitosterol （ 1 ）, Behenic acid （2）, 3β,20-dihydroxyl-5β-Pregnanes （ 3 ）, Kaempferol （4）, 13-amyrin （ 5 ）, β-amyrone （ 6 ）. CONCLU- SION ： Compounds 3β,20-Dihydroxyl-5β-Pregnanes （ 3 ）, β-amyrin （ 5 ） and 13-amyrone （ 6 ） are isolated from this plant for the first time.
