SUMMARY:

Tannins are polyphenols present in various groups of plants and are found in almost all parts of plants, have a physiological function of protection against herbivores and diseases, which can be characterized as hydrolyzable or condensed. Vegetable tannins are of relevant economic, ecological and social importance in the country's non-timber forest sector, sparking numerous studies in search of new species that produce tannins. This research aims to quantify the condensed tannins extracted from the bark of two forest species: Mimosa tenuiflora Willd and Mimosa caesalpiniifolia Benth and evaluate its potential as a coagulant for water treatment. The barks were collected from five trees that had appropriate phytosanitary characteristics for each species, obtained from a six-year-old forest plantation, grown for timber purposes. Located in the Experimental Area of the Academic Unit Specialized in Agricultural Sciences (UAECIA) of the Agricultural School of Jundiaí (EAJ), municipality of Macaíba-RN. Total solids content (TST), Stiasny index (I) and condensed tannin content (TTC) were determined. The species M. tenuiflora obtained higher percentages in all parameters TST, I and TTC (27.60%, 74.82% and 20.65% respectively), indicating potential for large-scale tannin production, although the M. caesalpiniifolia has presented lower TTC, TST values in I, the value was similar to that of black jurema with (71.43%), characterizing a high degree of pure tannins, requiring further research, such as chemical characterization for identification possible new uses for this species.
