A simple quantitative method using TLC-image analysis to determine fructooligosaccharides (FOS) in food samples was written by Muniz-Marquez, Diana Beatriz;Martinez-Cervantes, Marco Antonio;Martinez-Perez, Alain;Aguilar, Cristobal Noe;Aguilar-Zarate, Pedro;Wong-Paz, Jorge Enrique. And the article was included in Turkish Journal of Chemistry in 2022.Application of 470-69-9 This article mentions the following:
The thin-layer chromatog. technique (TLC) is a simple and inexpensive anal. commonly used to identify qual. the presence of carbohydrates in food samples such as mono- di and oligosaccharides particularly. TLC assay could be improved using image processing software for the semiquant. determination of this type of compound In the present work, TLC-image anal. with Silica Gel 60 TLC plates was used for the semiquant. determination of 6 standards of carbohydrates (glucose, fructose, sucrose, 1-kestose, nystose, and fructofuranosylnystose). Subsequently, the areas of the spots of each compound were determined by digitizing in a conventional office scanner. Then, the segmentation of the images is carried out using software for image processing. The calibration curves were plotted in the Excel software using the average of the areas of the pigmentations obtained in pixels. In this study, the technique of thin-layer chromatog. was also used to quant. determine the presence of carbohydrates in food samples such as honey, garlic, and onion. Values of determination coefficient (R2) greater than 0.97 in all the calibration curves were obtained. This technique could be useful for detecting carbohydrates (monosaccharides, disaccharides, and oligosaccharides) in anal. assays and food samples without needing specialized anal. equipment. In this work, it was possible to determine the concentration of carbohydrates in samples of garlic and onion that showed the presence of prebiotic carbohydrates in addition to sucrose, glucose, and fructose. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Application of 470-69-9).
(2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9) belongs to tetrahydrofuran derivatives. Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. THF (Tetrahydrofuran) is also used as a starting material for the synthesis of poly(tetramethylene ether) glycol (PTMG), etc.Application of 470-69-9
