Microbiol. Res. 267, 127260 (2023). HPTLC of lipids in a Glutamicum mutant ΔSYA, unable to synthesize trehalose constructed by deleting genes treS, treY and otsA in the three pathways of trehalose biosynthesis, on silica gel with chloroform - methanol - water - ammonia 65:25:1:3. Detection by spraying with 10 % sulfuric acid in methanol, followed by drying at 160 °C for 5 min. Further analysis by liquid chromatography mass spectrometry.
Microbiol. Res. 268, 127295 (2023). HPTLC of melanin produced by Streptomyces sp. strain MR28 on silica gel with ethanol - 75 % butanol - water 1:4:1. Detection by exposure to iodine vapor. The hRF value for melanin was 68.
Microbiol. Res. 266, 127215 (2023). HPTLC of β-manno-oligosaccharides mannobiose (1), mannotriose (2), and mannotetrose (3) in the fermented broth of adult-associated Bifidobacterium adolescentis DSMZ 20083 on silica gel with butanol - water - acetic acid 2:1:1 overnight (12-15 h). Detection by spraying with a mixture of 1 mg/mL orcinol, 75 % ethanol and 3.2 % sulfuric acid in water, followed by heating at 100 °C for 10 min. The method was used to determine the ability of adult-associated B. adolescentis DSMZ 20083 to utilize β-manno-oligosaccharides from guar gum, locust bean gum, konjac root, and copra meal generated using GH26 endo-β-mannanase (ManB-1601).
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. 137, 108790 (2022). HPTLC of ursolic acid and oleanolic acid in Ocimum species on silica gel with 1 % iodine solution in chloroform up to 1.3 cm. Plates were kept for 10 min, followed by developing with hexane - ethyl acetate - methanol 82:18:5. Detection by spraying with 1 % methanolic sulfuric acid.
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. 408, 135253 (2023). HPTLC of genotoxic compound zones in 33 oils on silica gel with chloroform - ethanol 5:1, up to 20 mm, then with n-hexane - diethyl ether 2:1, up to 40 mm, and finally with n-hexane - toluene 1:2 up to 60 mm. Detection in white light, UV 254 nm and 366 nm. Genotoxicity bioassay by spraying with Salmonella suspension with or without the S9 mixture (fraction from phenobarbital/β-naphthoflavone-induced lyophilized rat liver strain), followed by incubation at 37 °C for 3 h. The plate was dried and FDG (fluorescein di(β-D-galactopyranoside)) was sprayed, followed by incubation at 37 °C for 15 min. Cytotoxicity bioassay by spraying with MTT solution (0.2 % in phosphate buffer) after incubation with the Salmonella culture, followed by analysis under white light. Confirmative detection of aliphates was performed via a reagent sequence on the same plate by spraying with 1) Rhodamine 6B reagent, followed by detection in UV 366 nm and 2) phosphomolybdic acid reagent, followed by heating at 120 °C for 10 min, and documented at white light illumination.
