目的：系统研究卵叶远志Polygala sibirica地上部分的化学成分。方法：采用各种柱色谱方法进行分离，利用波谱数据鉴定化合物的结构。结果：分离、鉴定了10个化合物，其中6个为酮类化合物，分别为6 羟基 1,2,3,7 四甲氧基酮(1)；1,2,3,6,7 五甲氧基酮(2)；1,7 二羟基 2,3 亚甲二氧基酮(3)；1,7 二羟基 2,3 二甲氧基酮(4)；1,3,7 三羟基 2 甲氧基酮(5)；1,6,7 三羟基 2,3 二甲氧基酮(6)。此外还分离得到α 菠甾醇(7)；α 菠甾醇 3 O β D 葡萄糖苷(8)；角鲨烯(9)和远志糖醇(10)。结论：化合物1～10均为首次从本植物中分离得到。
Objective: To investigate the chemical constituents of the aerial parts of Polygala sibirica systematically. Method: The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data. Result: Ten compounds were isolated and identified as 6 hydroxy 1, 2, 3, 7 tetramethoxy xanthone (1); 1, 2, 3, 6, 7 heptamethoxy xanthone (2); 1, 7 didydroxy 2, 3 methylenedioxy xanthone (3); 1, 7 dihydroxy 2, 3 dimethoxy xanthone (4); 1, 3, 7 trihydroxy 2 methoxy xanthone (5); 1, 6, 7 trihydroxy 2, 3 dimethoxy xanthone (6); α spinasterol (7); α spinasterolic 3 O β D glucoside (8); squalene (9) and polygital (10). Conclusion: Compounds 1 10 were isolated from this species for the first time.
