HPTLC of ciprofloxacin (1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(piperazin-1-yl)quinoline-3-carboxylic acid hydrochloride) and degradation products (7-[(2-aminoethyl)amino]-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid and 7-amino-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid) on silica gel with chloroform - methanol - 25 % ammonia 43:43:14. Detection with 0.3 % methanolic ninhydrin solution and dimethylaminobenzaldehyde and quantitative determination by absorbance measurement at 277 nm.

J. Planar Chromatogr. 23, 353-358 (2010). TLC of aclarubicin and doxycycline on silica gel, RP-18, cellulose, polyamide 11, and HPTLC on silica gel and RP-18 with a wide range (from 0 to 100 %) of mixtures of n-alcohols with DMSO, hexamethyldisiloxane, acetonitrile, and water in chambers saturated with mobile phase at room temperature. Detection by spraying with sulfuric acid - methanol 1:4, anisaldehyde - methanol - acetic acid - orthophosphoric acid - sulfuric acid 1:100:10:10:5 (for cellulose) and 5 % aluminium chloride in methanol (for polyamide). The effect of mobile and stationary phases on the chromatographic behavior of the compounds was studied.

Quantitative determination by absorbance measurement at 366 nm. The hRf value for gatifloxacin was 42. Linearity was in the range of 20-1000 ng/zone. LOD and LOQ were 2.6 and 5.6 ng/zone. Intermediate/interday/intra-day precision was below 2 % (n=6). The method showed comparable results with a validated RP-HPLC mehod.

(yarrow) tinctures on silica gel with chloroform - acetone 99:1. Bioautography by dipping into suspensions of Bacillus subtilis, S. aureus, S. epidermidis, Pseudomonas syringae pv. maculicola, Xanthomonas campestris pv., Escherichia coli and Aliivibrio fischeri for 10 s. In the case of soil bacteria and human pathogens, the plates were incubated at 37 °C for 5 h, followed by dipping into a solution of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT; 0.05 g/90 mL) for 5 s and further incubation at 37 °C for 2 h. The hRF values for (1) and (2) were 33 and 66, respectively.

J. Planar Chromatogr. 30, 291-298 (2017). HPTLC of cefuroxime axetil and cefepime in human whole blood and urine on silica gel with chloroform – ethyl acetate – glacial acetic acid – water 4:4:1:3 for (1) and ethanol – 2-propanol – glacial acetic acid – water 4:4:1:3 for (2). Quantitative determination at UV 285 nm for (1) and 266 nm for (2). The hRF values for (1) and (2) were 89 and 21, respectively. Linearity was between 3-77 μg/mL for (1) and 3-38 μg/mL for (2). The intermediate precision (n=6) was <2 % for (1) and (2). LOD and LOQ were in the range of 40 and 470 ng/zone. Recovery rate ranged from 95.8 to 101.5 % for (1) and (2).
