Abstract:
quercitrin is a natural nutritional supplement, which belongs to the flavonoids in phytochemicals, and is rich in vegetables and fruits. Flavonoids are the largest class of polyphenolic compounds, which contain three benzene ring molecules in the basic structure and have the property of being insoluble in water. The physiological effects of quercetin on the human body include: Antioxidant, analgesic, anticancer, reducing the risk of hypertension and improving diabetes. At present, most of the literature is to use its antioxidant capacity to study, in recent years, there are related studies in sports to explore its efficacy. Therefore, this article through the previous related research of quercetin, find out the function that has been confirmed by the study to discuss, and further as a reference for future research.
