SUMMARY The HPLC method was used to analyze the qualitative composition and quantitative ratio of phenolic compounds of the canadensis grass (Erigeron canadensis L.). In the alcohol-water extract obtained by the method of extraction with heating, 22 substances were found, 17 of
them were identified: among them phenolcarboxylic acids, coumarins, flavonoids. A method for the spectrophotometric determination of the quantitative content of the sum of flavonoids in the herb of canadian small petals has been developed and its validation has been carried out. The following validation parameters of the method were established: precision (repeatability, intra-laboratory reproducibility), correctness (accuracy) and linearity.
