捕虫堇(Pinguicula vulgris L)是一种生长在潮湿地区的食虫植物,具有泻下作用。在该植物中曾发现安息香酸,反式桂皮酸和黄酮类化合物。本文报道从捕虫堇全草中分离鉴定出globularin,globularicisin, scutellarioside—Ⅱ, 1-o-p-cumaroyl-β-D-glucopyanoside等已知的环烯醚萜成分。干燥全草粉粉920克用5升丙酮在室温浸提两周,蒸去溶剂后得80克提取物,硅胶柱色谱分离,正已烷—EtOAc和CHCl_3—MeOH梯度洗脱,分出25克globularin和globularicisin无定形粉末, Pinguicula vulgris L is an insectivorous plant that grows in wet areas and has a diarrhea effect. Benzoic acid, trans-cinnamic acid and flavonoids have been found in this plant. In this paper, it is reported that globularin, globularicisin, scutellarioside-II, 1-o-p-cumaroyl-β-D-glucopyanoside and other known iridoid glycosides are isolated and identified from the whole plant. 920 g of dried whole grass flour was extracted with 5 liters of acetone at room temperature for two weeks. 80 g of extract was obtained after evaporation of the solvent. The residue was purified by silica gel column chromatography and eluted with a gradient of n-hexane-EtOAc and CHCl 3-MeOH to give 25 g. Globularin and globularicisin amorphous powder,
