Acta Chromatographica 14, 102-109 (2004). Investigation of the chromatographic behavior of amoxicillin, ampicillin, cephalexin, cloxacillin, doxycycline, tetracycline, erythromycin, gentamycin, streptomycin, and co-trimoxazole on titanic silicate inorganic ion-exchanger with organic, aqueous, and mixed aqueous organic mobile phases. Achievement of rapid separation of one antibiotic from numerous other antibiotics, as have many binary and ternary separations. Demonstration of the dependence of Rf values on the salt concentration of the mobile phase, and the existence of a linear relationship between FM and molarity of (NH4)2SO4 for some antibiotics in salting-out TLC using aqueous ammonium sulfate solution. Study of the effect of varying volume ratios of the binary mobile phase methanol - 0.1 M formic acid on the Rf values.

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.
J. Planar Chromatogr. 26, 215-225 (2013). HPTLC of gatifloxacin and 8 related substances on silica gel with methanol - 1,2-dichloroethane - ammonia - acetonitrile 28:72:5:5. 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.
J. AOAC Int. 98, 857-861 (2015). _x000D_TLC direct bioautography of apigenin (1) and α-linolenic acid (2) in Matricaria recutita L. (chamomile) and Achillea millefolium L.
