Abstract
The paper presents the results of the study of Juniperus communis L. (Cupressaceae) bark composition. It is shown that the juniper’s bark contains 3.5 times more extractives than its wood. Individual component composition of ethanol and petroleum extracts of J. communis bark was confirmed using gas chromatography – mass spectrometry. Difference in the component composition of ethanol and petroleum bark extracts was determined. The major constituents of J. communis ethanol extract are monosaccharides, disaccharides and resin acids; of petroleum extract – resin and fatty acids, and sterols. It has been established, that ethanol extract of J. communis bark exhibit high antioxidant activity. The ABTS radical inhibition activity of the bark alcoholic extract reached 86–87%. Based on the conducted research, it can be concluded that in the subarctic region the bark of J. communis is a source of valuable bioactive substances.
