Abstract
The article presents data on the study of commodity indicators of black, gray and heart-leaved alder leaves harvested from wild plants. The moisture content was determined for all the studied samples. Common ash. Ash insoluble in a 10% solution of hydrochloric acid, organic and mineral impurities, parts of the plant that have lost their natural color. The complexometric titration method determined the content of tannins in the raw material, the content of which in the amount of 4.56 to 8.59%, allows considering this type of raw material as a promising additional source of phytopreparations.
