title: Preparation of high-purity baicalein from Scutellaria baicalensis Georgi.
abstract: In this work, high-purity baicalein was prepared. In the process of preparation, baicalin was obtained from Scutellaria baicalensis Georgi by alkali-solution and acid-isolation methods, and then high-purity baicalein was obtained by hydrolysis of baicalin and column chromatography purification. The purified product was identified by FTIR, UV, (1)H NMR and HPLC, and the purity was found to be 99.35%.
