Title: Flavonoids from the Aerial Parts of Inula japonica
Abstract: AIM:To investigate the chemical constituents of the aerial parts of Inula japonica Thunb..METHODS:Compounds were isolated and purified by column chromatography with silica gel,Sephadex LH-20 and preparative HPLC.Their structures were identified on the basis of physicochemical properties and spectroscopic data.RESULTS:Nine flavonoids were isolated and elucidated as quercetin(1),5,7-dihydroxy-3,3',4'-trimethoxyflavone(2),spinacetin(3),axillarin(4),eupatin(5),casticine(6),apigenin(7),luteolin(8),and 6-hydroxyapigenin(9).CONCLUSION:Compounds 2,6 and 9 were isolated from this genus for the first time,and compounds 3-5 were isolated from this plant for the first time.
