Abstract
The paper presents results of the investigation of phenolic compounds of the bark of the Siberian larch (Larix sibirica Ledeb.) and the Dahurian larch (Larix gmelini (Rupr.) Rupr). The flavonoids, stilbenes, phenolic acids have been identified on the basis of chemical, chromatographic and spectral data. Quercetin-3-O-α-L-rhamnopyranoside has been found for the first time in the bark of the Larix genus. Phenolic compounds with pyrocatechol type of substitution of aromatic ring have been found to dominate in the phloem of the larch species considered.
