FIELD: medicine.
SUBSTANCE: method is based on measuring a flavonoid amount by differential spectral photometry, calculated as Cinaroside at wave length 400 nm, extracting in water and alcohol and using 70% ethanol as an extraction fluid; the total flavonoid amount calculated as Cinaroside and an absolutely dry raw material in percentage (X) is calculated by formula.
EFFECT: method enables measuring the total flavonoid amount as biologically active components having a basic therapeutic action.
