Chemical Constituents from the Ethyl Acetate Portion of Inula wissmanniana

Sixteen compounds were isolated from the ethyl acetate portion of the aerial part of Inula wissmanniana,including six flavonoids,five phenylpropanoids,and five other aromatic compounds.On the basis of spectral data,their structures were identified as luteolin(1),3-O-methylquercetin(2),5,6,4'-trihydroxy-3,7-dimethoxyflavone(3),artemetin(4),taxifolin(5),dihydrokaempferol(6),3,4-di-O-caffeoyl quinic acid(7),3,5-di-O-caffeoylquinic acid(8),C-veratroylglycol(9),2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone(10),caffeic acid(11),dibutylphthalate(12),3,4-dihydroxybenzoic acid(13),3-hydroxy-4-methoxybenzoic acid(14),p-hydroxybenzoic acid(15) and vanillin(16).All the compounds were isolated from this plant for the first time.
