摘要
目的:研究云南元宝枫叶的化学成分。方法:用常压硅胶柱色谱、薄层色谱及Sephadex LH-20柱色谱法对元宝枫叶的70%乙醇提取物进行分离纯化,通过MS和NMR等波谱分析方法对其分离产物进行结构鉴定。结果:从元宝枫叶70%乙醇提取物的石油醚部分和醋酸乙酯部分中分离得到7个化合物,分别鉴定为:β-谷甾醇(1),β-香树脂醇(2),β-香树脂醇乙酸酯(3),3,5-二羟基-4-甲氧基苯甲酸(4),紫云英苷(5),槲皮素-3-O-β-D-半乳糖苷(6)及槲皮素-3-O-α-L-鼠李糖苷(7)。结论:所有化合物均为首次从该植物中分离得到。
Objective： To study the chemical constituents from the leaves of Acer truncatum. Method： Various chromatographic techniques were used to isolate and purify the constituents. The structures of these compounds were elucidated on the basis of spectral analysis. Result： Seven compounds were isolated and identified as β-sitosterol （1）,β-amyrin （2）,β-amyrin acetate （3）, 3, 5- dihydroxy-4 -methoxybenzoic acid （4）, astragalin （5）, quercetin-3-O-β-D-galactoside （6）, and quercetin-3-O-α-L-rhamnoside （ 7 ）. Conclusion： All of compounds were isolated from this plant for the first time.
