目的:研究贵州糯米藤Gonostegia hirta的化学成分。方法:利用硅胶柱色谱、Sephadex LH-20柱色谱、ODS柱色谱等色谱技术对贵州糯米藤95%乙醇浸提物进行分离纯化,根据理化数据和波谱数据鉴定化合物的结构。结果:共分离得到9个化合物,分别鉴定为β-谷甾醇(1)、β-胡萝卜苷(2)、蔗糖(3)、表木栓醇(4)、木栓酮(5)、木栓烷(6)、齐墩果酸(7)、坡模酸(8)、常春藤苷元(9)。结论:所有化合物均为首次从贵州糯米藤植物中分离得到。
Objective: To study the chemical constituents of Gonostegia hirta in Guizhou province. Methods: The extracts of 95% ethanol from Guizhou glutinous rice vine were isolated and purified by silica gel, Sephadex LH-20 column chromatography and ODS column chromatography. The structures of the compounds were identified by physicochemical and spectral data. RESULTS: Nine compounds were isolated and identified as β-sitosterol (1), β-daucosterol (2), sucrose (3), epiclodextrin (4) Alkaloids (6), oleanolic acid (7), acid (8), ivy aglycone (9). Conclusion: All the compounds were isolated from the Guizhou glutinous rice vine for the first time.
