The synthesis of the title compound is described starting from 2,4,6-t
rihydroxyacetophenone and 2,4,5-trimethoxybenzoyl chloride. In additio
n 5,7-dihydroxy-2',4',5'-trimethoxyflavone, 5-hydroxy-6-methyl-7,2',4'
,5'-tetramethoxyflavone, 5,7,2',4',5'-pentamethoxyflavone and 8-methyl
-5,7,2',4',5'-pentamethoxyflavone were prepared and characterized.
