Two new flavonol glycosides, named polygalin H (1) and polygalin I (2), as well as the known compound polygalin D (3), were isolated from the whole plant of Polygala sibirica L. var megalopha Fr. Their structures were elucidated on the basis of spectroscopic data analysis. These flavonol glycosides exhibited strong inhibitory activities against xanthine oxidase in vitro. Their half-maximal inhibitory
从远志 sibirica L. var megalopha Fr 的全株中分离出两种新的黄酮醇苷,命名为 Polygalin H (1) 和 Polygalin I (2),以及已知的化合物 Polygalin D (3)。在光谱数据分析的基础上阐明了它们的结构。这些黄酮醇苷在体外对黄嘌呤氧化酶表现出很强的抑制活性。计算它们的半数最大抑制浓度 (IC50),分别为 9.48、8.31、16.00 μM。
