Planta Med Int Open 9(1), e60-e71 (2022). HPTLC of an ethanolic Soxhlet extract of Caulerpa racemosa (Caulerpaceae) on silica gel with petroleum ether – acetone 4:1. Detection under UV 366 nm and after derivatization by spraying with Liebermann-Burchard reagent acetic anhydride – sulfuric acid – ethanol 1:1:10. β-Sitosterol (hRF 38) was identified by comparison with a standard.
J. Planar Chromatogr. 36, 433-438 (2023). HPTLC of synthetic cannabinoids AM2201 (1), CP-47,497 (2), and JWH-018 (3) in seized samples on silica gel with cyclohexane - diethylamine 9:1. Quantitative determination by absorbance measurement at 280 nm for (2) and 315 nm for (1) and (3). The hRF values for (1) to (3) were 26, 73 and 55, respectively. Linearity was between 2 and 14 µg/zone for (3), 5 and 35 µg/zone for (1) and 50 and 350 µg/zone for (2). The intermediate precision was 23.0 % for (1), 16.6 % for (2) and 7.5 % for (3). The LOD and LOQ were 5.6 and 16.9 µg/zone for (1), 0.7 and 2.2 µg/zone for (2) and 1.9 and 5.6 µg/zone for (3). Average recovery was 84.0 % for (1), 105.1 % for (2) and 107.1 % for (3).
J. Ethnopharmacol. 320, 117404 (2024). HPTLC of lupeol and stigmasterol in the stem bark of Ficus benghalensis, Ficus glomerata, Ficus religiosa, Ficus infectoria, and Albizia lebbeck on silica gel with toluene - ethyl acetate - methanol - formic acid 38:5:5:20:1. Detection by spraying with anisaldehyde sulfuric acid. Qualitative identification under UV light at 525 nm.
J. Planar Chromatogr. 36, 191-200 (2023). HPTLC of gatifloxacin on silica gel impregnated with 20 mM levocetirizine and levosalbutamol as chiral selector at pH 5, with acetonitrile - methanol - triethanolamine 1:3:1. Detection by exposure to iodine vapor. The hRF values for (RS)-gatifloxacin were 46 and 86, respectively. The LOD for the enantiomer of gatifloxacin was 4.2 μg/zone and 4.9 μg/zone, respectively.
J. Planar Chromatogr. 36, 179-190 (2023). HPTLC of genistin (1), ononin (2), rutin (3) and luteolin-6-C-glucoside (4) in rutin commercial products on silica gel with ethyl acetate - methanol - glacial acetic acid - formic acid 11:1:1:1. Detection by derivatization with natural products polyethylene glycol reagent. Quantitative determination by absorbance measurement at 254 nm. The hRF values for (1) to (4) were 50, 46, 21 and 29, respectively. Linearity was in the range of 60-300 ng/zone for (1) to (4). Intermediate precisions were below 3 % (n=3). LOD and LOQ were 8 and 24 ng/zone for (1), (2) and (4), and 11 and 32 ng/zone for (3). Recovery was between 98.2 and 102.0 % for (1), 100.5 and 100.8 % for (2), 99.8 and 101.6 % for (3) and 99.7 and 100.3 % for (4).
