Abstract

The invention relates to a method for rapidly analyzing lipid components in bee pollen. The method comprises the following steps: using an ultra performance liquid chromatography and quadrupole-static electric field orbitrap high resolution mass spectrum coupling technique (UPLC-Q-Exactive Orbitrap MS), and using positive and negative ion monitoring mode, full-scanning and the function of automatically triggering a tandem mass spectrometry scanning to accurately realize precise quantification of lipid components in bee pollen from different plants, and providing the basis for the origin place of bee pollen, authenticity judgment, doping counterfeiting and functional nutriology research of bee pollen. The technology is high in resolution ratio and accurate in positioning, overcomes the problems of low accuracy and reliability in ingredient identification in the prior art, and is a novel efficient technology for lipid component analysis.

Description

technical field [0001] The invention belongs to the field of chemical analysis, in particular to a method for rapidly analyzing lipid components in bee pollen. Background technique [0002] Lipids, also known as lipids, are insoluble in water but easily soluble in fat solvents (alcohols, ethers, chloroform, benzene) and other non-polar organic solvents, esters formed by the dehydration condensation of fatty acids and alcohols and their derivatives Substances are collectively referred to as lipids, which include fats, waxes, steroids, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, phospholipids, etc. Its main physiological functions include energy storage, formation of cell membranes, and information transmission of membranes. Lipids are used today in the cosmetic and food industries. Lipids can be roughly divided into eight categories according to their amphipathic properties (both hydrophilic and hydrophobic): fatty acids, glycerides...
