摘要：
In this article, the group chemical composition of individual parts of the bark of the Betula pendula (Betulaceae) birch was determined at different tree heights. The part of the bark in the examined birch was found to be 14%, including 5.4% of the outer bark and 8.6% of the inner bark. The content of main groups of substances (cellulose, lignin, extractive and mineral substances, free acids, and carbohydrates) was evaluated in the outer and inner bark depending on the stem height.
