Detection by spraying with alpha-naphthol–sulfuric acid sugar-detection reagent followed by heating at 110 ºC for 5 min. Densitometry of glucose and raffinose at 515 nm. HPTLC of amino acids with four different TLC systems: on silica gel with preadsorbent zone, on RP-18 with concentrating zone, on cellulose F with n-butanol – acetic acid – water 3:1:1, and on ion-exchange sheets with citrate buffer of pH 3.3 (84 g citric acid monohydrate, 16 g NaOH, and 5.9 mL HCl 37% per L). Detection by spraying with ninhydrin reagent, followed by drying in air for 30 min and heating for 10 min at 110 ºC. Quantification by densitometry at 495 nm for histidine and 610 nm for tryptophan.

J. Planar Chromatogr. 19, 467-468 (2006). TLC of carbaryl (1-naphthylmethylcarbamate), a common derivative of the widely used N-methylcarbamate insecticide, on silica gel with n-hexane - acetone 4:1 in a saturated twin-trough chamber. After drying the plate was heating at 100 °C for 5 min, cooled, and sprayed successively with 5 % sodium hydroxide solution and with a 1:1 mixture of 2 % diphenylamine solution and 5 % formaldehyde solution. Visual detection of the blue-green zones carbaryl.

LC-GC Europe, The Applications 19, (2006). HPTLC of Actaea racemosa (black cohosh) extracts on silica gel with toluene - ethyl formate - formic acid 5:3:2 with chamber saturation for 20 min and at a relative humidity of 5 % (automatic development chamber ADC2 with molecular sieve). Detection by dipping in sulfuric acid reagent (20 mL of sulfuric acid in 180 mL of methanol) followed by heating at 100 °C for 5 min. Evaluation under daylight and under UV 254 and 366 nm. The method is specific for identification of black cohosh and for discrimination from different species of common adulterants.

Chromatographia 65 (3-4), 239-243 (2007). Description of a novel TLC densitometric method for the determination of solasodine in various Solanum species (Solanaceae). Solasodine does not show UV absorption therefore TLC of an ion pair complex of solasodine with an acid dye was performed. TLC plates developed by using a solvent with an organic acid ensured in situ color development of the complex. Densitometry at 461 nm. Linearity was 79.2 - 495 ng/zone, with a correlation coefficient of 0.995. The method shows good reproducibility, specificity and accuracy (98.54 ± 2.8%), and eliminates post derivatization steps and the problem of background interference. Validation of the method and application of the method to determine solasodine content in various herb samples, herb extract and their formulations, without matrix interference observed.

J. Liq. Chromatogr. Relat. Technol. 28, 1765-1775 (2005).
