目的:对倒地铃有效部位化学成分进行研究。方法 :利用硅胶色谱、聚酰胺色谱等方法进行分离纯化,通过波谱方法结合理化性质鉴定化合物结构。结果:从倒地铃有效部位中分离并鉴定了8个化合物,分别为:十五烷酸(1)、芹菜素(2)、原儿茶酸(3)、原儿茶醛(4)、正三十一烷醇(5)、毛蕊异黄酮(6)、芦丁(7)、槲皮素(8)。结论:8个化合物均为首次从该植物中分离得到。
Objective: To study the chemical constituents of the effective parts of fallen bell. Methods: Silica gel chromatography, polyamide chromatography and other methods were isolated and purified by spectroscopic methods combined with physical and chemical properties of compounds identified structure. Results: Eight compounds were isolated and identified from the effective sites of Rhizoma Polygoni cuspidatum, which were: pentadecanoic acid (1), apigenin (2), protocatechuic acid (3), protocatechuic aldehyde N-nonyl alcohol (5), calycosin (6), rutin (7) and quercetin (8). Conclusion: The eight compounds were isolated from this plant for the first time.
