Acta Chimica 124, 541-545 (1987). TLC on silica with benzene - acetone 30:1. Detection by spraying with 50% phosphoric acid and heating at 110°C for 10 min.

I. Activated granulocyte induced lipid peroxidation in red blood cells. Acta Veterinaria, 39, 175-185 (1991). TLC of amines on cellulose with butanol - pyridine - acetic acid - water 3:3:1:1. Detection by spraying with ninhydrin reagent.

J. Chromatogr. B 667, 185-187 (1995). HPTLC on silica with 1) dichloromethane - triethylamine 4:1 for developing upto 30 mm; 2) dichloromethane - toluene - triethylamine 5:4:1 for developing upto 60 mm, c) toluene for developing upto 90 mm. Enhancement of the fluorescence by dipping the plate for 5 sec in paraffin - hexane 37:100. Quantification by fluoro densitometry at 310 nm. Discussion of the degradation of dansyl polyamines due to the time interval between application of samples.

Biochemical Systematics and Ecology 28, 209-216 (2000). TLC of guanidine derivatives on silica gel with butanol - pyridine - acetic acid - water 4:1:1:2 or propanol - acetic acid - water 4:1:1. Visualization with Sakaguchi reagent.

J. Planar Chromatogr. 18, 67-72 (2005). TLC of trans-resveratrol (trans-3,5-dihydroxystilbene), semicarbazide and dimedone (as standards) on silica gel using different mobile phases; OPLC on silica gel with chloroform - methanol 10:1. After drying bioautographic detection by immersion in the bacterial suspension of Pseudomonas savastanoi for 25 s. Visualization with MTT either after a short draining period or after overnight incubation.

J. Planar Chromatogr. 21, 55-59 (2008). HPTLC of glucosamine on amino phase with methanol - ethanol - 25 % ammonia 1:1:1 in a saturated chamber. Detection by heating at 160 °C for 10 min. A Tidas TLC 2010 system was used for direct spectrophotometry of the HPTLC plates. Averaged glucosamine densitograms in the wavelength range 305 to 330 nm were obtained from the spectra.

J. Pharm. Sci. & Res. 2(2), 143-148 (2010). TLC of salbutamol sulphate (SS), bromhexine hydrochloride (BH), and etofylline (ET) in fixed dose formulation on hand-made silica gel plates with methanol – n-hexane 2:1. All three compounds were well separated with hRf values of 25 for SS, 71 for ET and 91 for BH. Detection at 254 nm as well as by exposure to iodine vapors. For spectophotometric quantification the bands of the selected drug in sample and standard mixture were scraped off, suspended in methanol, and the absorbance was measured at the maximum absorbance wavelength of each compound.

CBS 112, 9-11 (2014). HPTLC of sibutramine on silica gel with toluene - methanol 9:1 with chamber saturation for 20 min, developing distance 70 mm. Quantitative absorbance measurement at 225 nm. A polynomial calibration curve was established in the working range of 78-3022 ng. Intermediate precision was between 2-9 %. The hRF of sibutramine was 53. The recoveries were between 96-104 %. For confirmation the sibutramine zone was eluted from the plate with the TLC-MS Interface and identified by MS. Among 52 tested commercial slimming products 26 were adulterated with sibutramine.
