The aerial parts of Ageratum houstonianum afforded three new flavones, 5-hydroxy-6,7,8,2',4',5'-hexamethoxyflavone; 5,2'-dihydroxy-6,7,8,4',5'-pentamethoxyflavone and 5-hydroxy-6,7,2',4',5'-pentamethoxyflavone.The known 5,6,7,3',4',5'-hexamethoxyflavone was also isolated.Structural determinations involved spectral methods and chemical degradations. - Key Word Index: Ageratum houstonianum; Asteraceae; Eupatorieae; heptasubstituted and hexasubstituted flavones; structure determination.

Besides agecorynin C, eupalestin and lucidin dimethyl ether, two new highly oxygenated flavones were isolated from Ageratum houstonianum.Their structures were established by spectroscopic and degradative evidence as 5,6,7,8,2',3',4',5'-octamethoxyflavone and 5,6,7,2',3',4',5'-heptamethoxyflavone. - Key Word Index: Ageratum houstonianum; Asteraceae; Eupatorieae; new octasubstituted and heptasubstituted flavones.
