摘要
目的:进一步研究野葛Pueraria lobata干燥根的化学成分。方法:采用硅胶柱色谱法结合制备高效液相进行分离和纯化,根据理化性质和波谱数据进行结构鉴定。结果:分离并鉴定了22个化合物:β-谷甾醇棕榈酸酯(1),β-谷甾醇(2),葛香豆雌酚(3),羽扇豆醇(4),羽扇豆酮(5),邻苯二甲酸二异丁酯(6),邻苯二甲酸二(2-乙基)己酯(7),槐香豆素A(8),香豆雌酚(9),尿囊素(10),大豆苷元(11),芒柄花素(12),3′-甲氧基大豆苷元(13),芒柄花苷(14),3′-羟基大豆苷元(15),染料木苷(16),大豆苷(17),8-甲氧基芒柄花苷(18),5-羟基芒柄花苷(19),(-)-puerol B 2-O-glucopyranoside(20),(6S,9R)-长寿花糖苷(21)和蔗糖(22)。结论:化合物1,5~8,15,18,21和22为首次从野葛中分离得到,其中化合物1,5~7,15,18,21和22为首次从葛根属植物中分离得到。
Objective: To study the chemical constituents in the roots of Pueraria lobata.Method: Various chromatographic methods were employed to separate of chemical constituents and the spectroscopic methods were used to elucidate the structure.Result: Twenty-two compounds were isolated and characterized as β-sitosterol palmitate(1),β-sitosterol(2),lupeol(3),lupeone(4),puerarol(5),diisobutyl phthalate(6),bis(2-ethylhexyl) phthalate(7),sophoracoumestan A(8),coumestrol(9),allantion(10),dadzein(11),formononetin(12),3′-methoxy daidzein(13),ononin(14),3′-hydroxy dadzein(15),genistin(16),dadzin(17),8-methoxy ononin(18),sissotorin(19),(-)-puerol B 2-O-glucopyranoside(20),(6S,9R)-roseoside(21) and sucrose(22),respectively.Conclusion: Compounds 1,5-8,15,18,21 and 22 were isolated from P.lobata for the first time,and componds 1,5-7,15,18,21 and 22 were isolated from the genus Pueraria for the first time.
