Abstract:
:A rapid multiresidue method was developed for the determination of 20 pesticides in Radix paeoniae Alba of Chinese herb by ultrasonic wave extraction, silica gel column chromatography and gas chromatography (GC) with electron-capture detection (ECD) in this study, Mean recoveries of the method ranged from 74.45 to 115.14%. The validation of the proposed approach was verified on Isatis indigotica Fort, Pltycodon grandiflorum, Cotex mouta and Poria cocos of Chinese herbs; good recoveries were also obtained in the range of 72.51-113.47%, respectively.
