目的:对贵州产穗花南蛇藤化学成分进行研究。方法:穗花南蛇藤乙醇提取物用乙酸乙酯萃取,乙酸乙酯部分用薄层色谱,硅胶反复柱色谱分离纯化,并用波谱学方法进行结构鉴定。结果:从中分离并鉴定了5个化合物,分别为β-谷甾醇(1)、β-香树酯醇(2)、β-香树酯醇乙酸酯(3)、30-hydroxylup-20(29)-en-3-one(4)、3-oxolup-20-(29)-en-30-al(5)。结论:所有化合物均首次从该植物中分离得到。
Objective: To study the chemical constituents of Nostoc sphaeroides from Guizhou. Methods: The ethanolic extract of Celastrus orbiculatus was extracted with ethyl acetate. The ethyl acetate was separated and purified by TLC and silica gel column chromatography. The structure was identified by spectroscopy. Results: Five compounds were isolated and identified as β-sitosterol (1), β-amygdalin (2), β-amygdalin acetate (3) and 30-hydroxylup-20 29) -en-3-one (4), 3-oxolup-20- (29) -en-30-al (5). Conclusion: All compounds were isolated from this plant for the first time.
