J. Ethnopharmacol. 319, 117085 (2024). HPTLC of betaine in Sida cordifolia on silica gel with methanol - ammonia 3:1. Detection by dipping into modified Dragendroff’s reagent, followed by heating at 120 °C for 20 min. Qualitative analysis under UV light at 540 nm.
Trends Anal. Chem. 167, 117276 (2023). Review of extraction and chromatographic methods to evaluate active forms of fat-soluble vitamins in various matrices, including HPTLC for the analysis of vitamins K, D, carotenoids in pharmaceutical products, dietary supplements and complex matrices.
Food Chem. 426, 136606 (2023). Review of different aspects of vitamins B6 and B12, including methods of determination and respective matrices, with emphasis on chromatographic techniques. Detailed information regarding vitamin B6 and B12 concentrations determined in selected food matrices, along with the respective TLC and HPTLC analytical methods was described.
Molecules, 26 (24), 7683 (2021). Samples were ultrasound-assisted extracts of fruit puree and juice (pre-treated with sulfur dioxide or ascorbic acid) of Ananas comosus (Bromeliaceae) and Mangifera indica (Anacardiaceae). HPTLC on silica gel with toluene – ethyl acetate – methanol – formic acid 120:90:35:3. Detection under white light, UV 254 nm and 366 nm, before and after derivatization by immersion (2 s, 3 cm/s) into anisaldehyde sulfuric acid reagent and diphenylamine aniline reagent, followed by heating at 110 °C for 5 min. Effect-directed analysis using automated immersion: A) for free radical (DPPH•) scavengers; B) for enzymatic inhibition (acetyl-cholinesterase, tyrosinase); C) for activity against Gram-negative (Aliivibrio fischeri bioluminescence assay) or Gram-positive bacteria (Bacillus subtilis bioassay). Active compounds were far more present in puree than in juice extracts, and differences were also seen between cultivars. Ascorbic acid (hRF 37), used as additive for the mango puree, was active as antioxidant and as transiently disruptive for A. fischeri metabolism and bioluminescence.
J. Planar Chromatogr. 34, 513-520 (2021). HPTLC of curcumin (1), piperine (2) and ascorbic acid (3) in a combined marketed formulation on silica gel with chloroform - methanol - ether - glacial acetic acid 95:3:1:1. Quantitative determination by absorbance measurement at 254 nm for (3) and in fluorescence mode at 366 nm for (1) and (2). The hRF values for (1) to (3) were 65, 83 and 28, respectively. Linearity was between 620 and 3040 ng/zone for (1), 470 and 2380 ng/zone for (2) and 530 and 2670 ng/zone for (3). Interday and intra-day precisions were below 2 % (n=3).
J Chromatogr A, 1640, 461929 (2021). Study of the impact of different strains, culture media and parameters (temperature, time, rotational speed, and glucide and amino-acid supply) on the metabolite profile of bacteria. Samples were cultivation broths of Bacillus subtilis, B. licheniformis, B. pumilus and B. amyloliquefaciens, as well as their respective supernatant liquid-liquid extracts (apolar solvents only or QuEChERS method with acetonitrile and MgSO4 – NaCl mixture 4:1). HPTLC on silica gel (normal phase and RP-18), either as bands (for small volumes of extracts) or as areas for supernatants and bigger volumes of extracts. Extract areas were focused with a three-step procedure (up to 20mm with acetone, and twice with methanol); unextracted supernatants were focused twice with methanol and once with tetrahydrofuran, but the application zone of the plate had to be cut before development, due to the high matrix load. Development with ethyl acetate – methanol – water at different ratios after activation of the plate surface with magnesium chloride (33% relative humidity), evaluation in white light and UV. Detection of antibacterial compounds with Aliivibrio fischeri bioassay. Derivatization with primuline (for lipophilic substances) and diphenylamine aniline sulfuric acid reagent (for saccharides). This method allowed a fast comparison: A) of the patterns of the different strains (presence /absence and intensity of detected or antibacterial bands); B) of cultivation parameters: the number of metabolites increased with time, rotational speed (oxygen level), and at 37°C (vs. 30°C), whereas a minimal medium allowed the detection of more metabolites, due to the lower matrix load; C) of the impact of the extraction parameters: choice of the solvents (QuEChERS method had no advantage here), solvent – supernatant ratio (1:3 showed richer patterns than 1:1); D) of the HPTLC parameters used (better separation and resolution with normal phase vs. RP18 layers).
J. Food Sci. 85, 1781-1792 (2020). HPTLC of scented (joha) rice and black rice variety on silica gel with chloroform - methanol 19:1 + 0.1 % formic acid and butanol - acetic acid - water 4:1:5. Detection by spraying with p-anisaldehyde and visualization under UV light at 200, 250 and 350 nm. The husk of the selected rice varieties contained the nonpolar metabolites whereas the seeds contain nonpolar as well as polar metabolites.
Food Chem. 362, 130206 (2021). HPTLC of 5-methyl tetrahydrofolate (1), tetrahydrofolate (2), pteroyl glutamate (3), 5-formyl tetrahydrofolate (4) and 10-formyl tetrahydrofolate (5) in legume seeds on silica gel with ethyl acetate - methanol - water - acetic acid 18:5:4:1. Detection under UV light at 254 and 366 nm. Quantitative determination by absorbance measurement at 366 nm. The hRF values for (1) to (5) were 69, 56, 43, 22 and 18, respectively. The intermediate precision was below 2 % (n=6). The LOD and LOQ were 10 and 29 ng/zone for (1), 19 and 57 ng/zone for (2), 9 and 28 ng/zone for (3), 10 and 29 ng/zone for (4) and 13 and 40 ng/zone for (5), respectively. Average recovery was 97.5 % for (1), 98.4 % for (2), 97.5 % for (3), 97.6 % for (4) and 97.8 % for (5).
