Method for preparing baicalein

The invention discloses a method for preparing baicalein. According to the method, 2,6-dimethoxy-p-benzoquinone used as an initial raw material is subjected to reduction, Friedel-Crafts acetylation, claisen condensation, dehydrogenation oxidation cyclization and demethylation five reactions to obtain baicalein with high yield. The method uses low-price and easily-available initial raw material, reagent and the like, has few synthesizing steps, is easy and convenient to operate and easy for production control, has high product yield and high purity, and is suitable for large-scale preparation and production application of baicalein.
