Disclosed is a novel, simple, scalable and environment friendly process for the synthesis of Oroxylin A from Baicalin. Baicalm is esterified to obtain a methyl ester which is further selectively methylated to provide Oroxylin A gluciironide methyl ester which on de- glycosylation results in the formation of Oroxylin A.
