[Determination of selected secondary metabolites and extracts of Philadelphus coronarius L].
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.
