Overview
Quinone compounds mostly have phenolic or hydroxyl groups, and are mainly divided into four types of benzoquinone, naphthoquinone, anthraquinone and phenanthrenequinone compounds and their derivatives. They play an important role in the fields of medicine, pesticides, and dyes. Quinones play an important role in the enzymatic browning of fruits and vegetables, and may form covalent adducts with amino acids, peptides and proteins. These reactions may change the physicochemical and immunological properties of food proteins. Therefore, quinones are widely used as antioxidants, preservatives, coloring agents and flavoring agents in foods. UPLC-MS/MS has the characteristics of fast analysis speed, high selectivity, high sensitivity, high accuracy, high stability and high throughput. It is the main identification and quantitative analysis method of quinones and their metabolites, which increases researchers’ understanding of the functional analysis and mechanism of action of the active molecules of quinone compounds.
