Four new flavonol glycosides (1-4), polygalins D-G, together with 12 known flavonoids (5-16) were isolated from the aerial parts of Polygala sibirica L. The chemical structures of these compounds were characterised by NMR and ESI-MS spectroscopic data and acid hydrolysis results. This report is a continuous research work on the systematic chemical investigations of plants of the genus Polygala in our laboratory.
从西伯利亚远志（Polygala sibirica L.）的地上部分分离得到四个新的类黄酮糖苷（1-4），即 polygalins D-G，以及 12 个已知的类黄酮（5-16）。这些化合物的化学结构通过 NMR 和 ESI-MS 光谱数据以及酸水解结果进行了表征。本报告是我们实验室对远志属植物进行系统化学研究的连续研究工作。
