Biomed. Chromatogr. 10, 146-147 (1996). TLC on silica by developing twice with 1) ethyl acetate - isooctane - acetic acid 100:400:11, and 2) ethyl acetate - hexane 3:1. Detection by spraying with Triton X-100 - chloroform - petrol ether 1:9:30. Quantification by densitometry at 340 nm/> 540nm.

J. Pharm. Biomed. Anal. 39, 581-586 (2005). For post-production quality control of camptothecin derivatives irinotecan (CPT 11) and topotecan (TPT), HPLC and HPTLC methods have been developed which were suitable for identification, determination of purity and quantification. HPTLC on silica gel with methylene chloride - methanol - formic acid - water 82:24:2:1. After development, the plate was soaked in 15 % paraffin in n-heptane. Quantitative determination by fluorescence measurement at 366/>400 nm. The method was linear within the range of 100-1000 ng/mL for both CPT-11 and TPT. The method was validated for accuracy, precision, LOD, and LOQ.

HPTLC of levofloxacon, (-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[1,2,3-de]-1,4-benzoxazine-6-carboxylic acid, and amlodipine besylate (as internal standard) on silica gel, prewashed with methanol, with chloroform - methanol - acetic acid 58:39:3 in a twin trough chamber. Quantitation by densitometry at 300 nm (levofloxacin) and 350 nm (internal standard).

J. Chromatogr. B 877 (29), 3719-3723 (2009). HPTLC of gemifloxacin mesylate in human plasma, extracted with chloroform - acetic acid 59:1, on silica gel with ethyl acetate – methanol - ammonia 8:4:3. The hRf value of gemifloxacin mesylate was 33. Quantification by densitometry at 254 nm. The calibration curve was established in the range of 50 to 600 ng/spot. Recovery of gemifloxacin mesylate was between 80.0 and 86.2 %. The stability of gemifloxacin mesylate in plasma was confirmed with samples submitted to three cycles of freeze–thawing at -20 °C, and with samples stored on the bench for 12 h.
