Abstract: Ellman reaction is a simple and sensitive method to analyze cholinesterase activity. A homogenate from pig liver was studied to get the best reaction condition through Ellman reaction, and it was found that this cholinesterase was very sensitive to Methamidophos, its lowest inhibition concent ration to this cholinesterase was 2.o mg/ kg, and had good promise to be used in detecting organophosphate and carbamate pesticide residue in agricultural products.
