J. Planar Chromatogr. 33, 429-437 (2020). Review of the application of TLC and HPTLC for the analysis of vitamins covering the period of 2011-2019. The authors describe stationary and mobile phases for the TLC/HPTLC analysis of water and fat-soluble vitamins. The review highlightes that none of the papers reviewed showed the use of surfactants or ionic materials as impregnating agents or mobile phase modifers.
J. Planar Chromatogr. 33, 79-87 (2020). HPTLC of vitamin C in the dried fruit of Rosa laxa on silica gel with ethyl acetate - absolute ethanol - water 40:24:15. Quantitative determination by absorbance measurement at 273 nm. The hRF value for vitamin C was 61. Linearity was between 0.25 and 1.2 µg/zone. Intermediate precisions were below 2 % (n=6). Average recovery was 98.4 %.
J. Liq. Chromatogr. Relat. Technol. 30, 2245-2252 (2007). TLC of authentic vitamin B12 and extract on silica gel with 2-propanol - 28 % ammonia - water 7:1:2 and 1-butanol - 2-propanol - water 10:7:10 in the dark at room temperature. After drying agar containing basal medium and pre-cultured E. coli 215 was overlaid and then incubated at 30 °C for 20 h. After spraying with a methanolic solution of 2,3,5-triphenyltetrazolium salt corrinoid compounds were detected as red zones under white light.
J. Planar Chromatogr. 31, 367-376 (2018). HPTLC of folic acid (1) in the presence of its impurities pteroic acid (2) and para-amino benzoic acid (3) on silica gel with methanol – iso-propanol – water – glacial acetic acid 90:5:5:2. Quantitative determination by absorbance measurement at 280 nm. Linearity ranged between 0.4-4 μg/zone for (1), 0.1-1.5 μg/zone for (2) and 0.2-1.8 μg/zone for (3). LOD and LOQ were 132 and 398 ng/zone for (1), 33 and 99 ng/zone for (2) and 66 and 199 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery was 100.0 % for (1), 98.6 % for (2) and 100.7 % for (3). Results obtained by the HPTLC method showed no significant difference when compared with those obtained by applying the reported RP-HPLC method.
Anal. Chem. 56, 1600-1603 (1984). HPTLC of gibberellins A3 and A4+A7 on silica with cyclohexane - acetone 4:5. Detection/quantification after exposure to concentrated hydrochloric acid for 30 minutes. Fluorescence scanning at 366 nm / > 400 nm.
J. Planar Chromatogr. 3, 429-430 (1990). TLC of vitamin A derivatives (all-trans retinal, all-trans retinic acid, vitamin A acetate, vitamin A palmitate) on silica RP-2 and Kieselguhr impregnated with 10% paraffin in cyclohexane with methanol - water 19:1. Detection under UV 254 nm.
J. Chromatogr. 655, 39-43 (1993). TLC of thiamine, riboflavin and niacin on silica with methanol - water 30:70. Quantification by fiber-optic fluorometry.
