ABSTRACT
Obejctive To determine and compare britanin content in dried aerial parts and capitulum of Inula linariifolia Turcz from 7 different origins by HPLC. Methods Analysis was performed on Agilent Zorbax SB C18 (250 mm×4.6 mm, 5 μm). Acetonitrile and water were used as mobile phase for gradient elution at 1.2 ml/min. Column temperature was 30 ℃ and the detection wavelength at 212 nm. Results The results meet the requirements of the method validation in 2015 edition of Chinese Pharmacopeia. The average britanin content in dried aerial parts of Inula linariifolia Turcz is 0.125% vs 0.732% in capitulum, which is significantly different. Conclusion The established method is simple and convenient. It can be used for quality control of Inula linariifolia Turcz.
