J. Planar Chromatogr. 27, 2942-2955 (2014). HPTLC of propafenone hydrochloride in tablets on silica gel with chloroform - methanol - acetic acid 79:20:1. Quantitative determination by absorbance measurement at 316 nm. The hRF value for propafenone hydrochloride was 64. Linearity was in the range of 100-3200 ng/zone. The intermediate/interday/intra-day precisions were below 2 % (n=3). The LODs and LOQs were 20 and 80 ng/zone, respectively. Recoveries were between 99.5 and 102.2 %.

J. Planar Chromatogr. 27, 287-293 (2014). HPTLC of ciprofloxacin HCl (1) and moxifloxacin HCl (2) in industrial wastewater on silica gel with methanol - ammonia - methylene chloride 11:7:4. Quantitative determination by absorbance measurement at 278 nm. The hRF values for (1) and (2) were 43 and 54, respectively. Linearity was in the range of 250-2500 ng/zone for (1) and 1000-50000 ng/zone for (2). The intermediate/interday/intra-day precisions were below 1 % (n=3). The LOD and LOQ were 110 ad 335 ng/zone for (1) and 101 and 305 ng/zone for (2), respectively. Recoveries were between 79.6 and 91.5 % for both (1) and (2). Results were comparable to a HPLC method.
J. Ethnopharmacol. 158, 454-457 (2014). The authors described how the European Pharmacopoeia provides a legal and scientific reference for the quality control of medicines. The document highlighted HPTLC as a tool for the screening of herbal drugs containing certain contaminants, such as aristolochic acids._x000D_

HPTLC fingerprint of (1) cinnamic acid, (2) cinnamic alcohol, (3) coumarin, (4) 2-methoxy cinnamaldehyde, and (5) cinnamaldehyde in Cinnamomi Ramulus on silica gel with system 1 (cyclohexane - ethyl acetate 7:2) over a path of 8 cm, followed by air drying and second development with system 2 (cyclohexane - ethyl acetate - acetic acid 70:20:1), detection at UV 254 nm and UV 366 nm. The hRF values of (1) to (5) were 15, 28, 39, 51, and 56.
J. Liq. Chrom. Rel. Tech. 38, 521-531 (2015). HPTLC of pitavastatin calcium on silica gel with ethyl acetate – methanol – toluene – glacial acetic acid 40:10:50:1. Quantitative determination by absorbance measurement at 335 nm. The hRF value of pitavastatin was 40. Linearity was between 25 and 150 ng/zone. The LOD and LOQ were 5 and 14 ng/zone. The intermediate intra-day and inter-day precisions were below 2.9 % (n=3). Recoveries were found in the range of 100.2-102.4 %.
J. Planar Chromatogr. 27, 416-419 (2014). HPTLC of (1) cotinine and (2) trans-3'-hydroxycotinine in urine on RP-18 with acetonitrile - water 4:1. Quantitative determination by absorbance measurement at 260 nm. Linearity was in the range of 65-325 ng/zone (at a low calibration range) and 325-1300 ng/zone (at a high calibration range) for (1) and 62.5-312.5 and 312.5-1250 ng/zone for (2). The intermediate precisions were below 9 % (n=3). The LOD and LOQ were 13 and 38 ng/zone for (1) and 17 and 50 ng/zone for (2), respectively.
