METHOD FOR PREPARING HIGH PURITY SCUTELLARIN AGLYCONE

摘要

Provided is a method for preparing scutellarin aglycone. In the method, 5,6,7,4'-tetramethoxy flavone is used as raw material, and high purity scutellarin aglycone is obtained through four steps of demethylation, acylation, hydrolyzation, and refinement. The preparing method is characterized by a low synthesis cost, a short line, and a high reaction yield, and the product is easily purified, can implement industrialized production, and has a desired industrial application prospect.
