摘　　要：目的:对杨梅科杨梅属植物矮杨梅的茎进行化学成分研究。方法:采用甲醇回流提取、色谱法分离、波谱法鉴定结构。结果:从该植物茎中共分离鉴定出8个化合物,分别是β-谷甾醇(1)、taraxerol(2)、myricanol(3)、山柰素(4)、槲皮素(5)、杨梅素(6)、杨梅苷(7)、芦丁(8)。结论:文章首次报道了矮杨梅茎的化学成分,化合物2,4为首次从该植物中分离得到。Objective： The aim of this article was to study the chemical constitutes of the stem of Myrica nana. Method： Compounds were obtained through reflux extraction with MeOH, column chromatography for separation, and IR, MS and NMR were used for structural identification. Result： Eight compounds were isolated from M. nana, and identified as β-sitosterol （1）, taraxerol （2）, myricanol （3）, kaempferol （4）, quercetin （5）, myricetin （6）, myricitrin （7） and rutin （8）, respectively. Conclusion： The chemical constituents of the stem of M. nana were reported for the first time, and compounds 2, 4 were obtained from this plant for the first time.
