Areal and chemical composition of wild inulin-containing plants on the territory of RSO-Alania

Abstract

In the presented work, an assessment of the raw material resources of the roots and rhizomes of wild inulin-containing plants of high elecampane (Inula helenium L.), greater burdock (Arctium lappa L.), medicinal dandelion (Taraxacum officianale Wigg.) was carried out, the possible annual volume of harvesting of roots and rhizomes in the territory North Ossetia-Alania. In Russia, the volumes of inulin production are small, therefore, pharmaceutical industries are forced to use more expensive imported inulin, which increases the cost of diabetic products. In this connection, the search for new sources of inulin is relevant. It has been established that the possible annual volume of blanks is 3.0-3.5 tons of dry matter. The chemical composition, the content of biologically active substances of the investigated types of inulin-containing raw materials are analyzed. It was noted that in the roots and rhizomes of elecampane, the high content of inulin is 37.0% -39.4%, in the roots of dandelion officinalis - 36.1% -37.0%, burdock - 37.2% - 38.8%. The maximum amount of phenolic compounds 7.3% was found in the roots and rhizomes of elecampane, the minimum - in the roots of burdock 5.0%. The content of pectin compounds was: 12.0% of the mass of dry matter - in high elecampane, 10.4% of the mass of dry matter - in burdock and 10.0% of the mass of dry matter - in dandelion officinalis. Some fragmentation, lack of information on a more complete chemical composition of metabolites of species of the genera burdock, dandelion and elecampane opens up wide opportunities for subsequent researchers.
