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