J. AOAC Int. 101, 385-393 (2018). HPTLC of nifuroxazide and its impurities A, B, C and D on silica gel with ethyl acetate – acetone – methanol – ammonia 170:50:10:1. Quantitative determination by absorbance measurement at 230 nm. The hRF values for nifuroxazide and its impurities A, B, C and D were 67, 46, 86, 8 and 34, respectively. Linearity ranged between 10-100 μg/zone for nifuroxazide and 0.1-1.0 μg/zone for impurities A to D. LOD and LOQ were 28 and 84 ng/zone for A, 27 and 80 ng/zone for B, 24 and 73 ng/zone for C and 26 and 79 ng/zone for D. The intermediate precision was <1 % (n=3). Average recovery was 100.5 % for nifuroxazide, 100.2 % for A, 99.0 % for B, 100.0 % for C and 100.2 % for D.
J. Chromatogr. Sci. 57 (1), 81–86 (2019). HPTLC of of norfloxacin (NF), tinidazole (TZ) and its potential impurity 2-methyl-5-nitroimidazole (MNZ) on silica gel with chloroform – methanol - formic acid 75:10:3. Detection and quantitative determination by densitometry at 298 nm. The linearity was between 0.4–2.4, 0.4–1.6, and 0.2–1.2 μg/band for NF, TZ and MNZ, respectively.
