摘要
目的:对远志进行化学成分研究。方法:采用硅胶柱色谱、Sephadex LH-20、大孔吸附树脂等方法进行分离纯化,根据化合物的波谱数据确定化合物结构。结果:从远志氯仿部位分离并鉴定了8个化合物,分别为:7-羟基-1-甲氧基-2,3-亚甲二氧基酮(1)、1,7-二羟基-2,3-二甲氧基酮(2)、1,3,6-三羟基-2,7-二甲氧基酮(3)、7-羟基-1,2,3-三甲氧基酮(4)、1,2,3,6,7-五甲氧基酮(5)、1,3,7-三羟基-2,6-二甲氧基酮(6)、7-羟基-1-甲氧基酮(7)、1,7-二羟基-3,4-二甲氧基酮(8)。结论:其中,化合物1、6-8为首次从该植物中分离得到。
Objective: To study the chemical constituents from the root of Polygala tenuifolia. Methods: Silica gel,Sephadex LH-20 and ODS chromatographic techniques were used to study the chemical constituents of Polygala tenuifolia,and the chemical structures were elucidated by application of spectral data. Results: Eight compounds were obtained and their structure were identified as 7-hydroxy-1-methoxy-2,3-methylenedioxyxanthone( 1),1,7-dihydroxy-2,3-dimethoxyxanth one( 2),1,3,6-trihydroxy-2,7-dimethoxyxanthone( 3),7-hydroxy-1,2,3-trimethoxyxanthone( 4),1,2,3,6,7-pentamethoxyxanthone( 5),1,3,7-trihydroxy-2,6-dimethanoxyxanthone( 6),7-hydroxy-1-methoxyxanthone( 7) and 1,7-dihydroxy-3,4-dimethoxyxanthone( 8). Conclusion: Compounds 1,6,7 and 8 are isolated from Polygala tenuifolia for the first time.
