Gas Chromatographic Determination of Prochloraz in Ten Herbal Medicines

Jialun Wu, Jing Zhao, Tianyu Wang, Aoran Chen and Jian Xue

A method for determining prochloraz in ten herbal medicines is described. Pesticide standards were fortified into herbal medicines at 3 levels (0.005, 0.01 and 0.05mg/kg). Prochloraz reacts with pyridine hydrochloride and generates a hydrolysate, the 2,4,6-trichlorophenol which responded intensively in GC-ECD. The results showed average recoveries were between 76.6% and 105.1%. The method evidenced good accuracy and precision for monitoring prochloraz in ten herbal medicine samples. The limit of quantification (LOQ) was 0.005mg/kg. It is linear from 0.005 mg/L to 2.000mg/L. The regression equation is y=3816.1x-7.7835, R=0.9997.
