Heliyon 6(7), e04481 (2020). TLC of two successive stem-bark macerates (dichloromethane – methanol 1:1 and 0:1) of Kigelia africana (Bignonaceae) on unmodified silica gel, developed with dichloromethane – ethanol 19:1. Detection by spraying with stannic chloride (tin IV chloride) in chloroform – acetic acid – water 8:8:1 and heating at 100°C for 10 min. Visualization under UV showed terpenoids, phenols, steroids and flavonoids as indigo zones. The two extracts provided similar profiles but with different intensities.
J Pharm Bioallied Sci. 12(2), 139-145 (2020). An HPTLC method was validated for the fingerprint of flavonoids and other phenolic compounds (rutin, apigenin, luteolin, caffeic acid, chlorogenic acid, rosmarinic acid) in methanol macerates of dried aerial parts of five Lamiaceae (subfamily Nepetoideae: Dracocephalum moldavica, Lophanthus anisatus, Monarda fistulosa, Ocimum americanum, Satureja hortensis). HPTLC of extracts and standards on silica gel with chloroform – ethyl acetate – formic acid 5:4:1 or with ethyl acetate – formic acid – water 15:1:1. Detection under UV light before and after spraying with aluminium chloride 1 % in methanol. Rosmarinic acid was present and abundant in all extracts and was also quantified by densitometry at UV 366 nm without derivatization. The LOD was 29.2 µg/mL; the rosmarinic acid concentration range was between 12.6 mg/g (Lophanthus) and 24.8 mg/g (Dracocephalum).
J. Planar Chromatogr. 33, 547-565 (2020). HPTLC of seven species of the genus Justicia (J. adhatoda, J. beddomei, J. betonica, J. carnea, J. gendarussa, J. santapaui, J. wynaadensis) on silica gel with toluene - ethyl acetate 9:1 for n-hexane extracts and toluene - ethyl acetate 4:1 for chloroform extracts and toluene - ethyl acetate - methanol 7:3:1 for methanol extracts. Detection by spraying with anisaldehyde - sulfuric acid reagent, followed by heating at 105 °C for 5 min. Densitometric scanning at 254 nm, 366 nm and 550 nm.
J. Planar Chromatogr. 33, 631-646 (2020). HPTLC of azilsartan medoxomil (1) and chlorthalidone (2) on silica gel with toluene - methanol - ethyl acetate - formic acid 35:10:5:1. Quantitative determination by absorbance measurement at 241 nm. The hRF values for (1) and (2) were 55 and 36. Linearity was between 800 and 4000 ng/zone for (1) and 250 and 1250 ng/zone for (2), respectively. Intermediate precision was below 2 % (n=3). The LOD and LOQ were 15 and 44 ng/zone for (1) and 10 and 32 ng/zone for (2). Recovery was between 100.8 and 101.7 % for (1) and 99.4 and 101.0 % for (2).
J. of Chromatogr. Sci. 59 (6), 576-583 (2021). HPTLC of simeprevir (SMV) and sofosbuvir (SOF) on silica gel with ethyl acetate – hexane - methanol 5:4:1. The hRF of SMV was 67 and of SOF 43. Quantitative determination by densitometry at 273 nm. The linearity range was between 60-1000 ng/band for SMV and 70-1200 ng/band for SOF, with good correlation coefficients (0.9993-0.9997) for both. LOD was 15 and 22 ng/band and LOQ 44 and 66 ng/ band for SMV and SOF, respectively.
J. of Chromatogr. Sci. 59 (6), 536-547 (2021). HPTLC of pregabalin (PGB) and amitriptyline (AMT) as an active binary mixture in pure forms or in human biological fluids (plasma/urine) on silica gel with ethanol - ethyl acetate - acetone - ammonia solution 160:40:20:1. Detection by spraying with 3 % ethanolic ninhydrin solution. Quantitative determination by densitometry at 220 nm for AMT and 550 nm for PGB peaks after derivatization. The linearity range was 0.2 - 2.5 μg/band for PGB and 0.1-2.0 μg/band for AMT.
J. of Chromatogr. Sci. 59(5), 425–431 (2021). HPTLC of bromhexine hydrochloride (BHX), impurity B (IMB) and impurity C (IMC) on silica gel with hexane - acetone - ammonia solution 450:25:4. Quantitative determination by densitometry at 240 nm. The linearity was in the range of 0.40-10.00, 0.20-2.00 and 0.20-2.00 μg/band for BHX, IMB and IMC, respectively. Comparison with an HPLC method showed no significant differences regarding accuracy and precision.
J. of Chromatogr. Sci. 59 (2), 140-147 (2021). TLC of paracetamol (PC), propyphenazone (PZ) and caffeine (CF) in the presence of the two PC impurities 4-aminophenol and 4-nitrophenol, on silica gel with chloroform - toluene - ethyl acetate - methanol - acetic acid 60:60:10:20:1. Quantitative determination by densitometry at 220 nm.
