The method of the quantitative estimation of the total flavonoids in the flowers of Crataegus sanguinea Pall. by using of the differential spectrophotometry (analytical wave-length at 412 nm) and of state standard sample of hyperoside was developed. The contents of the total flavonoids in the Crataegus sanguinea flowers are varied from 1,41 to 1,84% (calculated on the hyperoside). The relative degree of the determination of the total flavonoids in developed method with confidence probability 0,95 is no more than +4,46%.
