Abstract:
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.
