Abstract:
A method for analyzing a dithiocarbamate pesticide is provided. The method includes the steps of: adding a crude drug, a preparation containing the same, or a treated product thereof, an aqueous acid catalyst solution, L-cysteine or a salt thereof, and an organic solvent for extraction to a reaction vessel, sealing the vessel, carrying out microwave irradiation, digesting a dithiocarbamate pesticide existing in the crude drug or the preparation containing the same into carbon disulfide, carrying out fractional extraction using the above organic solvent, and then analyzing the extract.
