Review of advances in the thin layer chromatography of pesticides: 2004–2006

Abstract

Applications of thin layer chromatography and high performance thin layer chromatography for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds are reviewed for the period from July 1, 2004 to November 1, 2006. Analyses are covered for a variety of samples, such as food, crops, biological, environmental, pharmaceuticals, and formulations, and for residues of pesticides of various types, including insecticides, herbicides, and fungicides, belonging to different chemical classes. In addition to references on residue analysis, studies such as pesticide-structure relationships, metabolism, degradation, and lipophilicity are covered, many of which make use of thin layer radiochromatography.

Phytochemical Profile of Asplenium aethiopicum (Burm. f.) Becherer Using HPTLC

“…Newton et al [15] and Mukhopadhyay [16] explained the demerits of substandard drugs. The chromatographic methods are provided as an alternative method of identification and authentication of crude drugs from its adulterants [17]. HPTLC separations and profiles are employed to solve many qualitative and quantitative analytical problems in a wider range [18,19].…”

Assessment of Organophosphate and Carbamate Pesticide Residues in Cigarette Tobacco with a Novel Cell Biosensor

“…Additionally, biosensors rarely provide a full spectrum of the compounds present in a sample [1, 5, 24]. One of the traits that make cell biosensors attractive as a clinical analytical tool is their considerable sensitivity, which is assumed to enable, in some cases, the possibility to detect just a single target molecule [13, 14].…”

“…Bioluminescence-based systems have been extensively used to monitor cellular stress responses, either by inducing the response at low analyte concentrations or by inhibiting the luminescence at higher concentrations [5, 10-15]. …”

Adsorptive Immobilization of Acetylcholine Esterase on Octadecyl Substituted Porous Silica: Optical Bio-analysis of Carbaryl

“…25 As a result, these methods of analysis are expensive and have limited sample capacities. In this study, we report an optical biosensor for flow injection analysis of carbamate pesticide residue based on the degree of inhibition of AChE.…”
