Abstract

The invention discloses a method for determining multiple illegally added chemicals in liquid health food at the same time and aims at providing a method which is easy, accurate and rapid to operate, can realize simultaneous analysis on 17 illegally added chemicals in the liquid health food and can be used for assisting qualitative screening and quantitative detection of illegally added chemicals in memory-improving health food. According to the technical scheme, the method for determining multiple illegally added chemicals in the liquid heath food at the same time sequentially comprises the following steps: 1) preparing standard solution; 2) drawing a standard working curve; 3) pretreating a sample; and 4) purifying. The method for determining multiple illegally added chemicals in the liquid health food belongs to the technical field of medicine detection.

Description

technical field [0001] The invention relates to a method for measuring illegally added medicines, in particular to a method for simultaneously measuring multiple chemical drugs illegally added in liquid health food, and belongs to the technical field of medicine testing. Background technique [0002] At present, the health functions of health food approved in my country include weight loss, alleviating physical fatigue, assisting in lowering blood fat, assisting in lowering blood pressure, assisting in lowering blood sugar, and assisting in improving memory. In recent years, with the increasing pressure of social competition and aging With the expansion of society, health products that help improve memory are entering people's study, work and life. Common functions include improving memory and supplementing brain nutrition. The health function of "assisting memory improvement" is mainly through supplementing the substances necessary for the normal operation of the brain, incr...
