Chromatographia 65 (1-2), 105-110 (2007). HPTLC of seven pharmaceuticals, enrofloxacine, oxytetracycline, trimethoprim, sulfamethazine, sulfadiazine, sulfaguanidine and penicillin G/procaine in production wastewater (obtained by solid-phase extraction on hydrophilic-lipophilic balance cartridges with methanol) on cyano phase with 0.05 M oxalic acid - methanol 81:19 after optimization of chromatographic separation by systematic variation of the mobile phase composition using genetic algorithm approach. Quantification by videodensitometry at 254 and 366 nm. Validation of the method by investigation of linearity ranges (1.5 - 15.0 µg/L for enrofloxacine, 100 - 500 µg/L for oxytetracycline, 150 - 600 µg/L for trimethoprim, 300 - 1100 µg/L for sulfaguanidine and 100 - 400 µg/L for sulfamethazine, sulfadiazine and penicillin G/procaine, R > 0.991), its mean recoveries (74.6 - 117.1% and 55.1 - 108.0% for wellspring water and production wastewater, respectively). Application of the method in determination of pharmaceuticals in wastewater samples from pharmaceutical industry.
Chromatographia 66 (11-12), 605-608 (2007). HPTLC of both isomers of cefpodoxime proxetil on silica gel plate with toluene - acetonitrile 3:2. Quantification by densitometry at 234 nm. The limit of detection and quantification was 150 and 400 ng/zone, respectively.
Chromatographia 67 (5-6), 487-490 (2008). Simultaneous determination of escitalopram oxalate and clonazepam in a combined tablet dosage form by HPTLC on silica gel aluminum plates with toluene - ethyl acetate - triethylamine 14:7:6. Quantification by densitometry at 258 nm.
Ind. J. Pharma Sci. 70(6), 798-800 (2008). HPTLC of plumbagin in Drosera burmannii Vahl on silica gel with toluene - glacial acetic acid 55:1 (for alcoholic extracts) and toluene - chloroform - glacial acetic acid 10:10:1 (for aqueous extracts) with chamber saturation for 60 min. Evaluation in visible light at 425 nm. The alcoholic extract showed seven components, the main zone with hRf value of 56 corresponded to plumbagin. The aqueous extract showed two zones but no plumbagin.
Talanta 78 (3), 874-884 (2009). Presentation of a sensitive, selective and precise stability-indicating method for the determination of clopidogrel bisulfate in presence of its alkaline degradate and in pharmaceutical formulations. TLC on silica gel with hexane – methanol - ethyl acetate 87:10:3. Quantification by densitometry at 248 nm in the range of 0.6–3 µg/band. Recovery was 99.9 %. Clopidogrel could be determined in the presence of up to 90 % of its alkaline degradate. Method selectivity was evaluated using laboratory prepared mixtures. The analysis of clopidogrel in pharmaceutical dosage forms is possible without interference from additives.
Acta Chromatographica 20(3), 463-473 (2008). TLC on silica gel with toluene – methanol – triethylamine 35:15:1. The hRf of atenolol and lercanidipine hydrochloride was 24 and 68, respectively. Detection and quantitative determination by absorbance measurement at 275 nm. The linearity was in the range of 2-12 µg/band for atenolol and 400–2400 ng/band for lercanidipine hydrochloride. The recovery was 98.9 % for atenolol and 99.7 % for lercanidipine hydrochloride.
J. Planar Chromatogr. 25, 54-59 (2012). HPTLC of propanolol in human serum on silica gel with chloroform-methanol 9:1 + 1 drop ammonia. Quantitative determination by absorbance measurement at 290 nm. Linearity was in the range of 5-100 ng/band. Intra-assay and inter-assay precision was in the range of 1.8-2.9 % (n = 3) and 3.5-3.9 % (n = 9), respectively. Limits of detection and quantification were 3.2 and 4.0 ng/band, respectively. Recovery was in the range of 96.4-98.8 % with an %RSD below 4.2 %.
