Objective: To establish SPME-GC method for rapid determination of organochlorine pesticide residues (OCPs) in Lonicerae Japonicae Flos by comparing solid-phase microextraction (SPME) with other three pretreatment methods. Method: OCPs in Lonicerae Japonicae Flos were analyzed according to the methods in Chinese Pharmacopoeia 2010 edition
Japanese Pharmacopoeia 16th revision
Manual for China National Food Contamination and Harmful Factors Risk Monitoring in 2014 and solid phase microextraction technology (SPME)
and the recovery rates were calculated respectively. Result: Recovery rates of the four different pretreatment methods were determined between 65% to 120%. Among the methods
there was fewer impurity interference in Chinese Pharmacopoeia 2010 edition method
Japanese Pharmacopoeia 16th revision method and SPME. Conclusion: The effect of 4 methods on OCPs in Lonicerae Japonicae Flos was analyzed
