Flavones in Herbal Drugs

Flavonoids have been found widely presented in herbal drugs and have a broad range of physiological applications, such as anti-inflammatory, antitumor, anti-oxidant. 

Chinese traditional medicine, Scutellariae Radix, is the dried root of Scutellaria baicalensis Georgi. Baicalin and baicalein are two active flavones in Radix Scutellariae. In China, the Public Health Department requires that the content of baicalin in Scutellariae Radix should not be less than 8.0%. A method based on CZE-ECD has been developed for the determination of baicalein and baicalin in Scutellariae Radix and its pharmaceutical preparations [30]. The contents of baicalin and baicalein in the investigated samples of Radix Scutellariae were determined to be 44.4-85.5 and 10.7-20.6 mg g respectively.
