摘　　要：目的:对矮杨梅(Myricanana)根进行化学成分分离研究。方法:采用柱色谱和薄层色谱分离,并通过各种波谱学方法对化合物的结构进行鉴定。结果:从矮杨梅根的95%乙醇提取物中分离鉴定了7个化合物,分别为β-谷甾醇(1)、myr-icanol(2)、myricanone(3)、熊果酸(4)、槲皮素(5)、杨梅素(6)和杨梅苷(7)。结论:除化合物5、6和7外,其它化合物均为首次从该植物中分离得到。AIM ： To study the chemical constituents of the root of Myrica narta cheval. METHODS ： The con- stituents were separated and purified by different methods of chromatography, and their structures were elucidated by UV ,IR,GM and NMR. RESULTS： Seven compounds were isolated from the root of Myrica nana cheval. Their structures were identified as/3-sitosterol （1）, myricanol （2）,myricanone （3）, ursolie acid （4）, quercetin （5）, myricetin （6） and myricitrin （7）. CONCLUSION： Except for 5, 6 and 7, the other compounds were obtained from this plant for the first time.
