Gas-liquid chromatographic determination of alpha-cyano-3-phenoxybenzyl alpha-isopropyl-4-chlorophenylacetate residues in cabbage. 1977

N S Talekar

A gas-liquid chromatographic method is described for residues of a synthetic pyrethroid, Sumicidin (alpha-cyano-3-phenoxybenzyl alpha-isopropyl-4-chlorophenylacetate), on cabbage. The plant material is Soxhlet-extracted with hexaneacetone (1+1) and subsequently cleaned up on Florisil with benzene-ethyl acetate (9+1) eluting solvent. Gas-liquid chromatographic analysis was performed on a 0.5 m x 2 mm stainless steel column containing 3% OV-101+3% Apiezon L on 80-100 mesh Gas-Chrom Q, with tritium electron capture detection. Sumicidin recovery was 97% when added at the 0.5 ppm level. Routine Sumicidin residue monitoring data are presented.

D011722	Pyrethrins	The active insecticidal constituent of CHRYSANTHEMUM CINERARIIFOLIUM flowers. Pyrethrin I is the pyretholone ester of chrysanthemummonocarboxylic acid and pyrethrin II is the pyretholone ester of chrysanthemumdicarboxylic acid monomethyl ester.	Pyrethrin,Pyrethroid,Pyrethroids
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
