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.
Some physical chemical characteristics of methyl-p-hydroxy-benzoate.) TLC on silica with toluene - ethyl acetate - acetic acid 72:24:3. Detection with Millon reagent (12.5 g HgNO3 in 12 ml conc. HNO3 + 30 ml water) and by UV 254 nm.
J. Planar Chromatogr. 8, 439-443 (1995). HPTLC of 12 PVC antioxidants (i.a. bisphenol A, AO2 - AO10, BHT, AO12); identification was based both on isocratic development and automated multiple development. The isocratic screening method is a three-part TLC system with a basic separation method and two group-separation methods. Automated multiple development achieves identification with a single chromatogram. Quantification was performed using three of the twelve antioxidants as examples with mixtures of petrol ether and ether containing acetic acid (1 mL). A) 3:2 for the basic separation, b) 1:1 for group I separation and c) 19:1 for group 2 separation. Detection under UV 254 nm. Mobile phase for AMD consisted of n-heptane and diethyl ether. Quantification by densitometry at 258 nm (absorbance), at 366 nm (fluorescence). Recovery of e.g. bisphenol A was 97% with a relative standard deviation of 2.1%.
Proc. Intern. Symp. on Planar Separations, Planar Chromatography 2001, pp. 277-281. TLC of oil samples used for deep-frying of foods (chicken filets) on silica gel with petroleum ether - ether - acetone 90:10:1. Visualization by spraying with a 10% solution of phosphorus-molybdic acid in ethanol as well as by drying at 100°C. Quantification by videodensitometry. Quick and practical TLC method.
Detection limit 300 -1000 ng for BHA, BHT and PG, resp. Also GC.
Kautschuk + Gummi - Kunstoffe 41 (9) 875-881 (1988). TLC of antioxidants IPPD (N-isopropyl-N'-phenyl-p-phenylene-diamine), 6PPD (N-1,3-dimethyl-butyl-N'-phenyl-diamine), N,N'-diaryl-PPD (N,N'-diaryl-p-phenylene-diamine) and TMQ (2,2,3-trimethyl-1,2-dihydroquinoline) on silica with chloroform - hexane - methanol - acetic acid 15:6:1:1. To remove plasticizers the TLC plate is chromatographed twice with petrol ether first. Detection by multi-wavelength scanning of UV absorbance at 240, 280, 320, 360 nm and visually by spraying with 3% ethanolic solution of 2,6-dichloroquinone-4-chlorimide. Additionally identification by recording of UV spectra. A further mobile phase system (toluene - hexane - methanol 29:15:6) is mentioned.
J. Planar Chromatogr. 15, 294-298 (2002). TLC of 8 N-phenylsuccinimide derivatives on silica gel and on silica gel impregnated with paraffin with n-hexane - dioxane and n-hexane - acetone resp. acetone - water in different ratios. Visualization under UV 254 nm. The RP TLC method can be successfully used for separation of the succinimide derivatives.
Chem. Pharm. Bull. 34, 174-181 (1986). Description of a method for determination of the antioxidative activities of chemicals. Application of 1 Ál mixture of linolenic acid and test sample in ethanol to HPTLC plate, and peroxidation at 80 °C for 20 min. Detection of the lipid peroxides produced by spraying with alpha-methylindole reagent. Measurement by densitometry at 557 nm. Expression of the antioxidative activity of the test sample as the amount required to inhibit the peroxidation of linolenic acid by 50 %.
