Abstract

The invention relates to a method for simultaneously detecting seven slimming chemical components which are illegally added to traditional Chinese medicine, health food or cosmetics. According to the method, an appropriate mobile phase and a reasonable elution gradient are adopted during liquid-phase separation, so that the slimming components needing to be detected are effectively separated within 12 min, the analysis time of a sample instrument is shortened by 88%, and the work efficiency is greatly increased. Additionally, the advantages of high separation ability of the HPLC (High Performance Liquid Chromatography) technology, high sensitivity and stronger qualitative ability of the mass spectrum and the like are combined, so screening and confirmation can be simultaneously completed during one operation. By using the method disclosed by the invention, the seven chemical components including sibutramine, fenfluramine, phenolphthalein, ephedrine, caffeine, N,N-bi-demethylation sibutramine and furosemide can be effectively separated, the inspection time can be shortened, and the slimming chemical components which are illegally added to the traditional Chinese medicine, the health food or the cosmetics can be accurately and effectively distinguished.

Description

technical field [0001] The invention belongs to the technical field of food and drug detection, and specifically relates to a method for simultaneously detecting seven illegally added weight-loss chemical components in traditional Chinese medicine, health food or cosmetics. Background technique [0002] As people pay more and more attention to healthy weight, weight loss has become the biggest topic of beauty lovers, and various weight loss products are produced accordingly. In order to make their products have a rapid and obvious weight loss effect, some merchants illegally add chemical ingredients that have weight loss effects (such as sibutramine, etc.) At the same time, it will cause harm to the user's health and may even be life-threatening. Therefore, it is urgent to establish a fast and accurate analytical method to detect the weight loss chemical components illegally added in traditional Chinese medicine, health food or cosmetics. [0003] At present, the determina...
