Use of flavonol compound in preparation of antihypoxic medicines or foods

The invention discloses a use of a flavonol compound, which is the use of the flavonol compound in the preparation of antihypoxic medicines, health-care foods or foods. The flavonol compound may be dihydromyricetin, myricetin, dihydroquercetin or quercetin. In the invention, the cell activity test experiment and antihypoxic test of the dihydromyricetin, myricetin, dihydroquercetin and quercetin are performed by adopting a methyl thiazolyl tetrazolium (MTT) method and H9C2 (a rat myocardial cell line). Results show that the four flavonol compounds all have obvious antihypoxic activity and can be used for preparing antihypoxic medicines, health-care products or foods.
