To study on the chemical consitituents of Lagotis brevituba.
The chemical consitituents were isolated by silica gel column chromatography, polyamide column chromatography and semi-preparative HPLC, and their structures were identified by spectroscopic methods.
Eight compounds were isolated and they were identified as beta-sitosterol (1), succinic acid (2), luteolin-7-O-beta-D-glucoside (3), uracil (4), apigenin (5), chrysoeriol (6), chrysoeriol-7-O-beta-D-glucoside (7), and apigenin-7-O-beta-D-glucoside (8).
Compound 4-8 were isolated from L. brevituba for the first time, and among them, compound 7 and 8 were isolated from genus Lagotis for the first time.
研究短筒兔耳草的化学成分。
采用硅胶柱色谱、聚酰胺柱色谱和半制备高效液相色谱法分离化学成分，并通过光谱方法鉴定其结构。
分离得到8个化合物，分别鉴定为β-谷甾醇（1）、琥珀酸（2）、木犀草素-7-O-β-D-葡萄糖苷（3）、尿嘧啶（4）、芹菜素（5）、 Chrysoeriol（6）、 Chrysoeriol-7-O-β-D-葡萄糖苷（7）和芹菜素-7-O-β-D-葡萄糖苷（8）。
化合物4-8首次从短筒兔耳草中分离得到，其中化合物7和8首次从兔耳草属植物中分离得到。
