This paper presents the findings of the study of the composition of phenolic compounds in black poplar leaves (Populus nigra L.). For the first time flavonoid compounds such as сalendoflavobioside (quercetin-3-O-neohesperidoside), rutin (quercetin-3-O-rutinoside), and ferulic acid (phenylpropanoid) have been extracted from the leaves of the black poplar by the methods of extraction and the following adsorption column chromatography on silica gel and on polyamide sorbent. The obtained substances were characterized with the use of UV-, 1H-NMR-, 13C-NMR-spectroscopy and mass spectrometry and also by means of the results of acid hydrolysis. The flavonoids are the dominant phenolic components of the raw material of this plant.
