Simultaneous determination of myricetrin, quercitrin and afzelin in leaves of Cercis chinensis by a fast and effective method of ionic liquid microextraction coupled with HPLC

In this study, the contents of myricetrin, quercitrin and afzelin in Cercis chinensis leaves were determined simultaneously by 1-butyl-3-methylimidazolium tetrafuoroborate [BMIM] BF4/70% ethanol microextraction combined with High Performance Liquid Chromatograph (HPLC) analysis.
