摘　　要：目的:研究黑鳗藤Stephanotis mucronata根正丁醇部位化学成分。方法:采用色谱法分离,运用多种波谱技术鉴定结构。结果:从黑鳗藤中分离得到4个三萜皂苷,分别为sitakisosideⅦ(1),sitakisosideⅥ(2),sitakiso-sideⅡ(3)和sitakisosideⅠ(4)。结论:4个三萜皂苷均为首次从黑鳗藤中分离得到。Objective： To study the chemical constituents from n-BuOH fraction of the roots of Stephanotis mucronata. Method： The compounds were separated by chromatographic methods. A combination of UV, MS, and NMR spectroscopic methods was applied to identify structure of these compounds. Result： Four oleane saponins were isolated and identified as sitakisoside Ⅶ （1）, sitakisoside Ⅵ （2）, sitakisoside Ⅱ （3）, and sitakisoside Ⅰ （4）. Conclusion： These four compounds were obtained for the first time from this plant.
