矮杨梅叶子化学成分研究

Chemical Constituents of the Leaf of Myrica nana

目的:对杨梅科杨梅属植物矮杨梅(Myrica nana Cheval)叶子进行化学成分分析。方法:采用甲醇回流提取、色谱法分离、波谱法鉴定其结构。结果:从该植物叶子中共分离鉴定出6个化合物,分别是β-谷甾醇(1)、齐墩果烯(2)、槲皮素(3)、芦丁(4)、杨梅素(5)、杨梅苷(6)。结论:化合物2为首次从该植物中分离得到。

Objective：To study the chemical constitutes of the leaf of Myrica nana Cheval. Methods：Using reflux extraction with MeOH, column chromatography for separation, and IR, MS and NMR for structural identification. Results：Six compounds were iso- lated from the leaf of M. nana,and identified as β-sitosterol （1）,3β-hydroxyolean-12-en （2）,quercetin （3）,rutin （4）, myricetin （5） and myricitrin （6）,respectively. Conclusion：Compounds 2 were obtained from this plant for the first time.
