摘要

[Objectives] The paper was to explore enzyme inhibition rate method for rapid detection of organophosphorus and carbamate pesticides in cowpea.[Methods]Acetylcholinesterase( ACh E) was added to cowpea extract,to determine the inhibition rate of extract against enzyme. The influences of different sampling methods and sampling parts on detection results were compared. [Results]The positive rate of standard sampling was 18. 18% higher than that of non-standard sampling,and the positive rate of samples collected from cowpea tail was 16. 67% higher than that collected from other parts. [Conclusions] Enzyme inhibition rate method is suitable for rapid detection of organophosphorus and carbamate pesticides in cowpea.
