whole plant of Enicostemma hyssopifolium (Willd.) Verd. (Gentianaceae) was collected at different growth stages and was shown to contain seven flavonoids: apigenin (I), genkwanin (II), isovitexin (III), swertisin (IV), saponarin (V), 5-O-glucosylswertisin (VI), and 5-O-glucosylisoswertisin (VII). Compounds VI and VII previously were unreported in nature. The yields of the flavonoids varied with the
Enicostemma hyssopifolium(Willd。)Verd的整个植物。(龙胆科)在不同的生长阶段被收集并显示含有七个类黄酮:芹菜素(I),Genkwanin(II),异维亭新(III),Swertisin(IV),皂角苷(V),5-O-葡萄糖基维他命(VI)和5-O-葡糖基异维他汀(VII)。先前没有报道过化合物VI和VII。类黄酮的产量随生长期而变化。评价了这些结果的生化和化学分类学意义。
