| Abstract: | Three new flavonoids: 5-hydroxy-7-(3-methyl-2,3-epoxybutoxy)flavanone,5-hydroxy-3,8-dimethoxy 7-(3-methyl-2,3-epoxybutoxy)flavone and 4′-hydroxy-5-methoxy-7-(3-methyl-2,3-epoxybutoxy)flavone were isolated and identified from the aerial parts of Achyrocline flaccida. Tamarixetin, gnaphaliin, isognaphaliin, 5,7,8-trihydroxy-3-methoxyflavone, chrysoeriol, galangin 3-methyl ether, naringenin 5-methyl ether, caffeic acid, chlorogenic acid and isochlorogenic acid were also isolated. |
