Webused as an extraction solvent a mixture of acetone–hexane 1:1 and ethyl acetate–hexane 2:1 and 1:1. These solvent mixtures were transferred to the cell, which then was heated and pressurized to the selected conditions. The recovered extract was collected in amber glass vials, and the cell was flushed and purged with gaseous nitrogen. WebOBJECTIVE: The study aims at reporting a multiresidue analytical method for 126 different pesticides in raw material biomass as well as extracts of plants, which are widely used as ingredients in ayurvedic medicines as well as dietary supplements using LC-MS/MS and GC-MS/MS with a rugged sample preparation technique for accurate results.
