The plants of the families Salicaceae, Fagaceae, Pinaceae are traditional sources of tannins. However, earlier in the leaf tissues of some marine (Enhalus, Thalassia) and freshwater (Stratiotes) genuses of the family Hydrocharitaceae, idioblasts containing condensed tannins were found. In this regard, the purpose of the study was to determine the content of tannins in the phytomass of plants of the family Hydrocharitaceae (Hydrocharis morsus-ranae, Hydrilla verticillata, Stratiotes aloides, Egeria densa, Elodea canadensis) and medicinal plants − traditional sources of tannins (Quercus robur, Urtica dioica, Bidens tripartita).As a result of the research hydrolyzed tannins has been found in Hydrocharis morsus-ranae, and a mixture of hydrolyzed and condensed tannins in Stratiotes aloides, Elodea canadensis, Egeria densa, Hydrilla verticillata. Stratiotes aloides (3.1±0.1% of dry matter) and Hydrilla verticillata (2.8±0.1%) are characterized by the greatest content of tannins, Elodea canadensis (1.1 ± 0.1%) characterized by the minimal content. The shelf life of the dried phytomass does not affect the content of tannins. Statistical processing of the results of determination of tannins in the phytomass Hydrocharis morsus-ranae, Stratiotes aloides and Elodea canadensis, performed in different years, showed their convergence.The results of these studies allow us to consider the plants of the family Hydrocharitaceae as a potential source of tannins, comparable to such official sources as Urtica dioica and Bidens tripartita.
