2',3',4',5,5',6,7,8-Octamethoxy- (Ia) and 2',3',4',5,5',6,7-heptamethoxyflavone (IIa) and their position isomers substituted with tetramethoxyl groups in ring B were synthesized to confirm the structures of agehoustin A and agehoustin B isolated from Ageratum houstonianum. The characteristics of the synthesized flavones were investigated by spectroscopic methods.
