Abstract: The extraction methods for optimum conditions and the general esterase activity of phytoesterase were studied. The paper also researched the sensitivity of phytoesterase extracted from different plant seeds on assaying organophosphate pesticides, and the limits of detection concentration(LDC) of five pesticides were determined. Results showed that the general esterase activity and the sensitivity of the phytoesterase obtained from soybean are the best.

Key words: phytoesterase, organophosphate pesticides residue, abstract methods, the limit of detection concentration (LDC)
