摘要
目的：研究半边莲Lobelia chinensis Lour.全草的化学成分。方法：用溶剂提取、萃取、硅胶正相柱色谱及结晶法进行化学成分的分离纯化，通过理化性质和波谱分析鉴定结构。结果：从半边莲全草中分离鉴定了7个化合物，结构分别为：5-羟基-4′ -甲氧基黄酮-7-O-芸香糖苷（1），正丁基-O-β-D-吡喃果糖苷（2），5，7-二甲氧基香豆精（3），cirsiumaldehyde（4），香叶木素（5），5-hydroxymethyl-2-furancarboxaldehyde（6）和6-羟基-7-甲氧基香豆精（7）。结论：化合物2～4，6，7为首次从该植物中分离得到。
Objective： To study the chemical constituents from Lobelia chinensis. Method： The constituents were extracted with 95% EtOH, partitioned with different solvents, and isolated and purified by silica gel column chromatography and crystallization, their structures were elucidated by physico-chemical properties and spectroscopic data. Result： Seven compounds were isolated from the titled plant. They were identified as 5-hydroxy-4′-methoxyflavone-7-O-rutinoside （1）, n-butyl-O-β-D-fructopyranoside （2）, 5,7-dimethoxycoumarin （3）, cirsiumaldehyde （4）, diosmetin （5）, 5-hydroxymethyl-2-furancarboxaldehyde （6）, and 6-hydroxy-7-methoxycoumarin （7）. Conclusion： Compounds 2-4, 6, and 7 were obtained from the titled plant for the first time.
