J. Planar Chromatogr. 37, 261-269 (2024). HPTLC of amlodipine besylate (1) and azilsartan (2) mixture in human plasma on silica gel with toluene - ethyl acetate - methanol - acetone - acetic acid 12:3:2:1:2. Quantitative determination by absorbance measurement at 244 nm. The hRF values for (1) and (2) were 22 and 63, respectively. Linearity was between 60 and 600 ng/zone for (1) and 90 and 900 ng/zone for (2). The inter-day and intra-day precision was below 3 % (n=6). The LOD and LOQ were 14 and 42 ng/zone for (1) and 19 and 56 ng/zone for (2), respectively. Recovery was between 99.1 and 102.2 % for (1) and (2).

Detection by spraying with anisaldehyde - sulfuric acid reagent, followed by heating at 105 °C for 3-5 min. Quantitative determination by absorbance measurement at 520 nm. The hRF values for (1) to (3) were 41, 27 and 19, respectively. Linearity was between 200 and 600 ng/zone for (1) to (3). The inter-day and intra-day precision was below 2 % (n=6). The LOD and LOQ were 13 and 39 ng/zone for (1), 18 and 55 ng/zone for (2) and 13 and 41 ng/zone for (3), respectively. Average recovery was 97.4 % for (1), 97.7 % for (2) and 97.0 % for (3).
