| Abstract: | The antioxidant AO] properties of the ethylacetate extract of Larix sibirica bark and the flavonoids quercetin and dihydroquercetin found in it were studied using a model radical-chain oxidation of
propan-2-ol in the kinetic regime. The quantitative characteristics of their AO activity were determined as effective rate
constants fkln. It was found that dihydroquercetin had the highest AO activity among the studied natural compounds.
