59th Indian Pharmaceutical Congress F-94, 413, (2007). HPTLC of escitalopram oxalate and clonazepam in combined tablet dosage form on silica gel aluminium plate with toluene - ethyl acetate - triethylamine 7:3.5%:3. Quantitative determination by densitometric scanning at 258 nm. The calibration curve was linear over a range of 250 and 2500 ng/zone for escitalopram oxalate, and 50 and 500 ng/zone for clonazepam.

J. Planar Chromatogr. 30, 299-306 (2017). HPTLC of itopride (1), pantoprazole (2), and mosapride (3) in human plasma on silica gel with methylene chloride ‒ ethyl acetate ‒ methanol ‒ 25 % ammonia 60:10:4:1. Quantitative determination by absorbance measurement at 289 nm. The hRF values for (1), (2) and (3) were 22, 41 and 62, respectively. Linearity was between 100 and 1500 ng/zone for (1) and (3), and between 70 and 1500 ng/zone for (2). The intermediate precision (n=3) was <2 % for (1) to (3). LOD and LOQ were 33 and 98 ng/mL for (1), 17 and 51 ng/mL for (2) and 30 and 91 ng/mL for (3). Average recovery rate was 99.2 % for (1), 99.1 % for (2) and 99.6 % for (3).
