| خلاصه مقاله | Water-soluble vitamins primarily belong to the vitamin B complex group, essential nutrients in foods, especially infant formulas. These vitamins have been engaged in metabolic pathways and show significant health benefits when added to our daily diet [1]. According to the Food and Drug Administration (FDA) and food and supplement manufacturers, there are daily nutritional requirements for these vitamins, so quantitatively assaying the vitamin amount in such products is necessary. However, simultaneous measurement of these two vitamins in food is complicated due to the complexity of the sample environment and the small concentration of vitamins [2]. A magnetic Mg/Fe layered double hydroxide (magnetic LDH) nanocomposite was successfully prepared and used as a suitable adsorbent to simultaneously extract vitamins B1 and B6 from complex infant formula and food supplements. As-prepared nanoadsorbent was successfully in magnetic solid phase extraction setup with no hazardous solvents and extraction performed in 6 min. The structure of nanoadsorbnet is lamellar, providing a wide surface to extract the analytes. The quantification of the analytes was accomplished using the liquid chromatography-tandem mass (LC/MS-MS) technique. Under optimum extraction conditions, the linearity ranged from 4 to 1000 ng/mL (vitamin B1) and 20 to 1000 ng/mL (vitamin B6), and the correlation coefficients (R2) was better than 0.999. The intra-day (n = 3) and inter-day precisions (n = 3 working days) calculated in the form of percent relative standard deviations (%RSDs) were below 7%. The proposed method was successfully practiced for the analysis of vitamins B1 and B6 in several brands of infant formulas and food supplements. |
