The aim of this study was to quantify extracts from the bark and green fruits of A. colubrina and M. tenuiflora, compared to A. mearnsii bark using the formaldehyde method. Ten M. tenuiflora and ten A. colubrina trees were selected to collect the studied material and five A. mearnsii individuals. Moisture content, total solids, Stiasny index and condensed tannin content were analyzed. The results were compared by Tukey test at 5% probability. In relation to the Stiasny index, the species A. mearnsii and M. tenuiflora did not differ statistically, with averages of 68.3 and 62.6%, respectively. The content of condensed tannins found in A. colubrina fruits, did not differ statistically from the content of the bark of the same species, corroborates with data referenced in the literature in research with this species that is traditionally exploited in the Northeast Region of Brazil by the tannery industry. The M. tenuiflora and A. colubrina species present potential for the production of tannic extracts, although tannin contents are inferior to those obtained for A. mearnsii. In addition, due to the abundance in the Brazilian semiarid region, the M. tenuiflora has potential for exploitation to obtain tannins.

Keywords :

Vegetable components; phenolic compounds; tannins extraction; stiasny method.
