Development of modern approaches to assessing the quality of quercetine-containing dietary supplements

Abstract

Quercetin is a natural bioflavonoid with pronounced antioxidant, anti-inflammatory, membrane-stabilizing and immunomodulatory properties, which leads to its widespread use in medicines and dietary supplements. At the same time, low water solubility quercetin, variability of bioavailability and dependence of quality on the source of plant raw materials necessitate increased requirements for quality control of products containing it. A pressing problem of the modern market of dietary supplements is the lack of unified and scientifically based approaches to assessing the quality of such products, comparable to the requirements for medicines. The aim of the work was to theoretically substantiate the draft specification and determine modern approaches to quality control of a dietary supplement containing quercetin.
