Development of Solvent System for Detection of Methyl Parathion in Vegetables

In modern day practices, the use of pesticides provided unquestionable benefits by increasing the production of crop. It has the drawback of pesticide residues which remain on the vegetables, constituting potential health risk to consumer. This leads on the one hand to the establishment of legal directives to control their levels through the maximum residue level (MRLs) and on the other to continue search for pesticides, which are less persistent and less toxic for human being. In present study attempt has been made to develop solvent extraction method for detection of organophosphorous pesticides methyl parathion in cauliflower by using Thin Layer Chromatography. A total five solvent systems have been developed The data performed hRf value, Hexane: Benzene (60:40). Hexane: Benzene: Petroleum ether (60:30:10) & Hexane: Benzene : Chloroform (70:20:10) are given the best result. This method offers cheap, time saving, easy and safe alternative to typical multiresidue analysis in vegetables samples.
