摘要
目的:研究欧亚旋覆花的黄酮类化学成分。方法:用95%乙醇提取欧亚旋覆花,并用各种柱色谱分离纯化,通过测定理化常数和光谱分析鉴定其结构。结果:分离得到10个黄酮类化合物,经鉴定为菠叶素(1)、6-甲氧基-木犀草素(2)、木犀草素(3)、槲皮素(4)、异鼠李素(5)、山柰酚(6)、芦丁(7)、万寿菊苷(8)、异槲皮苷(9)和槲皮苷(10)。其中,化合物5、7、10为首次从欧亚旋覆花植物中得到。结论:本试验可为欧亚旋覆花的进一步研究提供科学依据。
OBJECTIVE: To study the flavonoids in Inula britannica .METHODS: The Inula britannica was extracted with 95% ethanol and isolated and purified by different column chromatography, the structures of the constituents were derived by measuring the physicochemical constants and spectral analysis. RESULTS:A total of 10 flavonoids were isolated from Inula britannica which were stated as follows:Spinacetin(1) ,6- methoxy - luteolin(2), Iuteolin(3) ,Quercetin(4), Isorhamnetin(5), Kaempferol(6), Rutin(7), Patulitrin(8), Isoquercitrin(9) and Quercitrin(10) .Of which, compounds 5, 7 and 10 were isolated from Inula britannica for the first time. CONCLUSION: This result serves as a scientific basis for the further study of Inula britannica .
