The paper deals with the determination of selected secondary metabolites in the branches and leaves of Philadelphus coronarius L. Colorimetric methods were employed to determine the content of flavonoids (0.63 % and 0.01 %, respectively) and phenolic substances (3.25 % and 0.70 %, respectively) in leaves or branches. Also the content of extractive substances was determined in ethanolic, aqueous-ethanolic (85 % and 60 % ethanol), and aqueous extracts. This yielded 9.56 %, 22.46 %, 24.93 %, and 33.15 % of extractive substances in leaves and 2.20 %, 6.04 %, 8.84 %, and 10.39 % of extractive substances in branches.
