Abstract

The invention belongs to the technical field of chemical ingredient detection, and particularly relates to a method for detecting multiple kinds of vitamin simultaneously. According to the detecting method, multiple lipid-soluble vitamin samples contained in a sample can be fast and accurately measured simultaneously through a two-dimensional liquid chromatographic analysis method. According to the method, effluent in a specific period of a one-dimensional chromatographic column is injected to a two-dimensional chromatographic column, effluent of the two-dimensional chromatographic column is subjected to vitamin D measurement, the other effluent of the one-dimensional chromatographic column is subjected to measurement of non-vitamin D lipid-soluble vitamin, peakoverlap of vitamin D and other lipid-soluble vitamin can be avoided, and the influence of lipid matter in the sample on the detection accuracy of vitamin D is effectively reduced. According to the detecting method, the normal-phase column purifying process on vitamin D in a traditional method can be omitted, tedious detecting steps are simplified, detection time is saved, and high accuracy can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of chemical component detection, and in particular relates to a method for simultaneously detecting multiple vitamins. Background technique [0002] Vitamins A, D, and E are fat-soluble vitamins necessary for the body to maintain normal metabolism. Vitamin A (Retinol), also known as retinol, has the functions of promoting body growth, maintaining epidermal integrity and vision; vitamin D mainly includes vitamin D 2 (ergocalciferol) and vitamin D 3 (cholecalciferol), which can promote calcium and phosphorus metabolism and bone formation in mammals; vitamin E is also known as tocopherol, mainly including α-tocopherol, β-tocopherol, γ-tocopherol and δ-tocopherol Among them, α-tocopherol has the highest activity, which has the functions of promoting fertility and anti-aging. Therefore, in the food industry, vitamins A, D, and E are often added, but because these vitamins are relatively unstable, they are very...
