目的:研究菊科植物准噶尔橐吾的化学成分。方法:采用硅胶和制备薄层方法进行分离纯化,运用核磁、红外和质谱等技术鉴定化合物结构。结果:从准噶尔橐吾95%乙醇提取物中分离鉴定了10个化合物,分别为:苯并呋喃艾里莫芬-2-烯(1)、6-当归酰氧基-1,10-环氧-euryopsin(2)、2-hydroxyplatyphyllide(3)、艾里莫芬-1β-羟基-6,9-二烯-8-羰基-11-降-11-酮(4)、2-异丙烯基-6-乙酰氧基-8-甲氧基-13-苯并二噁英-4-酮(5)、艾里莫芬-1β-羟基-6,9-二烯-8-羰基-11-降-11-羟基(6)、isopetasin(7)、艾里莫芬-6β,10α-二羟基-1-羰基-7(11),8(9)-二烯-8,12-内酯(8)、艾里莫芬-10α-羟基-1-羰基-7(11),8(9)-二烯-8,12-内酯(9)、呋喃艾里莫芬-6β-当归酰氧基-1β,10β-环氧-9-羰基(10)。结论:其中,化合物2-9为首次从该植物中分离得到。
Objective: To study the chemical constituents of Ligularia songarica. Methods: Isolation and purification were carried out on repeated silica gel column chromatography. The compounds structures were identified by physico-chemical properties and spectral analyses. Results: Ten compounds were isolated and identified as benzofuranoeremophil-2-ene(1),6-angeloyloxy-1,10-epoxy-euryopsin(2),2-hydroxyplatyphyllide(3),1β-hydroxy-6,9-dien-8-oxoeremophy-11-nor-11-ketone(4),2-isopropenyl-6-acetyl-8-methoxy-13-benzodioxin-4-one(5),1β-hydroxy-6,9-dien-8-oxo-11-nor-11-hydroxyeremophilane(6),isopetasin(7),6β,10α-dihydroxy-1-oxoeremophila-7(11),8(9)-diene-8,12-olide(8),10α-hydroxy-1-oxo-eremophila-7(11),8(9)-diene-8,12-olide(9) and 6β-angeloyloxy-1β,10β-epoxy-9-oxo-furaneremophilane(10). Conclusion: Compounds 2 - 9 are obtained from this plant for the first time.
