Food Res. Int. 157, 111198 (2022). Review of applications on the range of rapid non-invasive and destructive technologies developed for evaluating the adulteration of different powdered horticultural products, including HPTLC methods. The paper described the analysis of black pepper from adulterated samples with papaya seed powder.
Food Chem. 145, 109482 (2023). Review of analytical techniques and applications to assess authenticity of honey and detect adulterants, including TLC and HPTLC. In addition, HPTLC fingerprinting of lipophilic fractions of honey of various botanical sources.
Chinese Medicine 10, 13 (2015). Samples were root and rhizome extracts of Panax notoginseng (Araliaceae), either raw or in the form of commercial granules. Standards were ginsenosides Rg1, Rb1, Rd, Re and Rg2, notoginsenoside NR1. TLC on silica gel with chloroform – ethyl acetate – methanol – water 15:40:22:9, followed by 10 min air drying. Derivatization for ginsenosides by immersion into sulfuric acid (10 % in ice cold methanol), followed by 10 min air drying and 5 min heating at 100 °C. Quantification by densitometric fluorescence measurement (deuterium and tungstene lamp, 366 nm). For each standard the linear range was 0.05-1 mg/mL (LOQ comprised between 38 and 431 µg/µL). As NR1 and Re (ratio ca. 2:1) had almost the same hRF, they were quantified together as one substance. Multivariate analysis through hierarchical (HCA) and principal component analyses (PCA) was used to order the samples into two clusters, according to the analyte concentrations, the raw plant extracts being richer than most of the commercial products. This TLC method was compared to quantification through UPLC-PDA (Ultra-performance liquid chromatography with photo diode array), which was more sensitive (LOQ between 10 and 49 µg/µL) but did not allow the separation between Rg1 and Re (ratio ca. 6:1).
Food Control. 136, 108840 (2022). HPTLC of flavonoids, coumarins, sesquiterpene lactones and phenolic acids in German Chamomile (Matricaria recutita L.) on silica gel with ethyl acetate - methanol - water - acetic acid 200:25:20:1 and ethyl acetate - toluene 2:1. Detection of flavonoids and phenolic acids by spraying with Natural product reagent. Detection of sesquiterpene lactones by spraying with anisaldehyde sulfuric acid reagent. Qualitative analysis under UV light at 366 nm. Principal component analysis (PCA) was used for reducing data dimensionality and representing samples across principal components.
Food Chem. 134184 (2023). HPTLC of 45 berry cultivars belonging to the nine species strawberry, raspberry, blackberry, black currant, blueberry, gooseberry, cape gooseberry, chokeberry, and goji berry on silica gel with toluene - ethyl acetate - formic acid - water 15:30:5:3. Detection by dipping into a 0.5 % solution of 2-aminoethyl diphenylborinate in ethyl acetate, followed by drying and dipping into a 5 % solution of PEG 400 in dichloromethane. Qualitative analysis under UV light at 366 nm.
Food Chem. 133108 (2022). HPTLC of 135 baobab samples (Adansonia digitata) from different agroecological regions on silica gel with toluene - ethyl acetate - methanol - formic acid - water 60:50:25:3:5. Detection by dipping into aniline diphenylamine o-phosphoric acid reagent, p-amino benzoic acid reagent, or p-anisaldehyde sulfuric acid reagent, followed by heating at 120 °C for 5 min. Qualitative analysis under UV light at 254 nm. fluorescence detection at 366 nm and white light illumination.
Food Chem. 133610 (2022). HPTLC of hormonal active compounds in 68 different botanicals on silica gel with ethyl acetate - toluene - formic acid - water 16:4:3:2. The plate was neutralized by spraying with citrate phosphate buffer (6 g/L citric acid monohydrate and 10 g/L disodium hydrogen phosphate in double-distilled water, adjusted to pH 12 by solid sodium hydroxide). To overcome diffusion caused by long bioassay incubation, zone fixation was achieved by coating with polyisobutyl methacrylate (0.25 % Degalan in n-hexane), followed by drying. The prepared yeast cell culture was piezoelectrically sprayed onto the plates, followed by incubation at 30 °C for 4 h. The substrate solution (2 mg 4-methyl umbelliferyl-β-D-galactopyranoside in 100 μL dimethyl sulfoxide and 3 mL citrate buffer) was piezoelectrically sprayed, followed by incubation at 37 °C for 1 h, dried, and documented by fluorescence light detection at 366 nm. The resulting NP-HPTLC–UV/Vis/FLD–pYAVAS–FLD bioassay allowed the detection of androgens, antiandrogens, false-positive antiandrogens, and synergists in complex mixtures.
J. AOAC Int. 104, 19-25 (2022). HPTLC of xipamide (1) and triamterene (2) on silica gel with toluene - methanol - ethyl chloride - acetic acid 35:10:5:1. Quantitative determination by absorbance measurement at 300 nm. The hRF values for (1) and (2) were 52 and 37, respectively. Linearity was between 0.3 and 7.0 µg/zone for (1) and 0.3 and 12.0 µg/zone for (2). Inter-day and intra-day precisions were below 2 % (n=3). The LOD and LOQ were 47 and 141 ng/zone for (1) and 75 and 228 ng/zone for (2), respectively. Mean recovery was 100.2 % for (1) and 100.8 % for (2).
