title: [Plant drugs with residues of organochlorine compounds. 2. Identification of residues of DDT and its analogs by comparison of gas chromatography on packed and capillary columns and GC/MS coupling].
abstract: For the GC analysis of DDT isomers and metabolites in extracts of Flores Chamomillae end Radix Valerianae the separation on a packed QF-1/OV-17 column was compared with various capillary columns of the CP-Sil type. Identification of the individual compounds could be achieved by comparing the retention behavior, chemical transformation of DDT and DDE, as well as by capillary GC-MS using single ion monitoring of substance-characteristic ion mass. In this way, residues of p,p'-DDT, o,p'-DDE and p,p'-TDE could be identified.
