Abstract
A process for preparing oroxylin A includes: subjecting baicalin to a methylation reaction using a methylating reagent in the presence of a base to methylate the 6-hydroxyl group of baicalin, so as to form a methylated compound; and subjecting the methylated compound to a deglucuronidation reaction in the presence of an acid, so as to form oroxylin A.
