Hawthorn is an important edible plant belonging to the Rosaceae family and has a wide range of uses in traditional medicine. In the 19th century, tea made from hawthorn flowers and leaves began to be used as a blood purifier, and since the early 20th century, hawthorn fruits and flowers have been recommended as a remedy for heart and vascular diseases. The biological properties, medical and traditional uses of the Crataegus meyeri Pojark. species selected as the research object were investigated, and the antiradical activity of flavonoids from the fruits against the free radical DPPH was investigated. The relationship between the structure of flavonoids and their radical activity was determined. The results obtained show that the radical neutralizing effect of flavonoids directly depends on the substitution feature of free hydroxyl groups in the flavonoid structure. It was revealed that the presence of 3-OH and 3,4-dihydroxy groups in the flavonoid molecule is decisive for the antiradical activity.
