楮头红化学成分研究

Studies on the Chemical Constituents of Sarcopyramis nepalensis

目的:对楮头红进行化学成分研究。方法:采用不同的色谱技术进行分离,用波谱数据确定化合物的结构。结果:分离鉴定了10个化合物:(E)-1-(3,4-二羟基苯基)丙烯酸乙酯(Ⅰ)、硬脂酸(Ⅱ)、软脂酸(Ⅲ)、对羟基苯甲酸(Ⅳ)、3,4-二羟基苯甲酸(Ⅴ)、龙胆酸(Ⅵ)、没食子酸(Ⅶ)、β-谷甾醇(Ⅷ)、β-胡萝卜苷(Ⅸ)、豆甾醇硬脂酸酯(Ⅹ)。结论:化合物Ⅰ、Ⅳ、Ⅴ、Ⅵ、Ⅶ为首次从该植物中获得。

Objective ： To study the chemical constituents of Sarcopyramis nepalensis. Methods ： The constituents were isolated and purified with chromatography and the structures were elucidated by spectral analysis. Results： Ten compounds were isolated and their structures were identified as ： （E） -1-（ 3,4-dihydroxy-phenyl） ethyl acrylate（ Ⅰ ）, stearic acid（ Ⅱ ）, palmitic acid（ Ⅲ ）, 4-hydroxybenzonic acid （ Ⅳ ）, 3,4-dihydroxy benzoic acid （ Ⅴ ）, gentisie acid （ Ⅵ ）, gallic acid （ Ⅶ ）, β-sitosterol （ Ⅷ ）, daucosterol （ Ⅸ ）, stigmasterolstearate（ Ⅹ ）. Conclusion： Compounds Ⅰ , Ⅳ, Ⅴ, Ⅵ, Ⅶ are isolated from this plant for the first time.
