从卵叶远志(Polygala sibirica)根中分离出6种新的蔗糖酯卵叶远志糖(sibiricose)A_1~A_6(1~6),2种新的(口山)酮碳苷卵叶远志(口山)酮(sibiricaxanthone)A(7)、B(8),1种新的苯乙酮苷卵叶远志苯酮(sibiricaphenone)(9),同时修订了已知(口山)酮苷——远志(口山)酮Ⅲ(polygalaxanthone)(10)的结构。 干燥卵叶远志根粉末(660g)用3倍量甲醇回流提取,减压回收溶剂,甲醇提取物混悬于水,上Diaion HP-20柱,依次用50%、70%、100%的甲醇水溶液洗脱,50%的甲醇洗脱液经硅胶柱分离,制备型
Six new sucrose esters, sibiricose A_1~A_6 (1~6), were isolated from the roots of Polygala sibirica, and two new ketoroglycosides from the genus Polygala sibirica were isolated. Sibiricaxanthone A(7), B(8), a new acetophenone sibiricaphenone (9), and a modification of known ketoroglycosides - Polygala. (Mouth hill) Structure of ketone III (polygalaxanthone) (10). The dried eggplant Polygala tenuifoliae powder (660 g) was extracted with 3 times methanol and refluxed. The solvent was recovered under reduced pressure. The methanol extract was suspended in water and applied to a Diaion HP-20 column, followed by 50%, 70%, and 100% methanol in water. Elution, 50% methanol elution on silica gel column, preparative
