(Oxidation of nicotine and chelating agent by mercury(II)-compounds). Pharmazie 62, 7-13 (2008). TLC of nicotine on silica gel with chloroform - ethanol - ammonia 80:20:1. Detection by spraying with Dragendorff reagent. TLC of iminodiacetic acid on silica gel with n-propanol - water 7:2 or with n-butanol - acetic acid - water 4:1:1. Detection by spraying with ninhydrin reagent.
J. Planar Chromatogr. 22, 457-458 (2009). TLC of monocrotophos and biological extracts, dimethoate, endosulfan, carbaryl, and cypermethrin on silica gel with chloroform - acetone 7:3 with chamber saturation. Detection by spraying with 5 % sodium hydroxide solution followed by 5 % benzil reagent (5 g benzil in 100 mL acetone) and heating at 100 °C for 10 min. Monocrotophos was detected as a pink zone in daylight.
J. Planar Chromatogr. 24, 113-115 (2011). TLC of dichlorvos on silica gel with cyclohexane - acetone - methanol 16:6:1. Detection by spraying with 2 % sodium hydroxide solution and subsequent spraying with 2 % thiobarbituric solution followed by heating at 90 °C for 10 min. The hRf of dichlorvos was 50. The limit of detection was approximately 18 µg/zone. Spectrophometric analysis of dichlorvos was performed by measuring the absorbance of the sample solution. The linearity was in the range of 50-350 µg/mL dichlorvos. On alkaline hydrolysis dichlorvos forms dimethylphosphoric acid and dichloroacetaldehyde; the latter reacts with 2-thiobarbituric acid to give a sharp pink spot. The reagent is selective for dichlorvos, and does not react with other organophosphorus, organochlorine, carbamate, and synthetic pyrethroid insecticides.
J. Planar Chromatogr. 25, 262-268 (2012). HPTLC of paraquat (1), diquat (2), difenzoquat (3), mepiquat (4), and chloromequat (5) in water on silica gel with 1-propanol - methanol - 2.5 N NaCl 1:1:3. Quantitative determination by absorbance measurement between 500 and 535 nm. The hRf values of compounds (1) to (5) were 21, 30 36, 52 and 56, respectively. Limits of quantification were 5 ng/zone for (1), 2 ng/zone for (2), 25 ng/zone for (3), 15 ng/zone for (4) and 9 ng/zone for (5). Recovery rates for compounds (1) to (5) were 50.7, 65.2, 59.6, 45.1 and 33.7 %, respectively.
J. Planar Chromatogr. 27, 477-479 (2014). HPTLC of N,N-dimethyltryptamine in seized street samples on silica gel with methanol – ammonia 200:3. Quantitative determination by absorbance measurement at 220 nm. The hRF value of N,N-dimethyltryptamine was 50. Linearity was in the range of 11.5-34.2 μg/zone. The intermediate precisios were below 5 % (n=3). The LOD and LOQ were 3.3 and 9.9 μg/zone, respectively. Mean recovery was 117.9 %.
ecotoxicological study with the Steatoda grossa spider web
J. Planar Chromatogr. 31, 7-12 (2018). HPTLC of L-histidine (1), L-glycine (2), L-alanine (3) an L-phenylalanine (4) in Steatoda grossa spider web on silica gel with 2-butanol – acetone – glacial acetic acid – water 7:7:2:4. Detection by spraying with 0.5 % solution of ninhydrin in methanol, followed by heating at 100–110 °C for 10 min. Quantitative determination by absorbance measurement at 500 nm. The hRF values for (1) to (4) were 11, 35, 48 and 72, respectively. Linearity was between 0.2 and 1.0 μg/zone for (1) and (2), 0.1 and 0.5 μg/zone for (3) and 0.3 and 1.5 μg/zone for (4). LOD and LOQ were 185 and 556 ng/zone for (1), 154 and 461 ng/zone for (2), 100 and 302 ng/zone for (3) and 152 and 456 ng/zone for (4).

Fungal toxins (orellanine, orellinine) extracted with methanol from cortinarius orellamus and other species and their photodecompositon (UV) products are separated on silica with cyclohexane - ethyl acetate 3:1 and visualized by Fe2+ or Fe3+ reagents. Also 2-dimensional technique.
Anal. Proc. 21, 432-434 (1984). Application of the Mean List Length concept to identification of unknown drugs (MLL concept: determination for a given substance, for a given system or combination of systems, how many other substances from the total population would qualify for identification. The shorter the MLL the better is the system for systematic toxicological analysis. With MLL -1 the individual substance can be identified unequivocally against all other substances in the set.) 100 basic and neutral drugs. 8 systems.
