Abstract

The invention discloses a method for simultaneous determination of various chemical drugs illegally added in solid health food, aiming to provide a method which is easy to operate, accurate and fast, and can realize the simultaneous analysis of 17 kinds of illegally added chemicals in solid health food, which can be used Qualitative screening and quantitative detection of illegally added chemicals in health food that assists in improving memory; its technical scheme is as follows: the method includes the following steps in sequence: 1) preparation of standard solution; 2) standard working curve; 3) Sample pretreatment; 4) Purification; belongs to the technical field of medical testing.

Description

technical field [0001] The invention relates to the determination of illegal pharmaceutical additives, in particular to a method for simultaneous determination of multiple chemical drugs illegally added to solid health food, and belongs to the technical field of medical detection. 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 b...
