extracts from </span><i><span style=\"font-family:Verdana;\">S. adstringens </span></i><span style=\"font-family:Verdana;\">accessions
collected in 12 distinct locations were investigated in order to determine the
rates of tannins in inner barks and to validate </span><i><span style=\"font-family:Verdana;\">S. adstringens </span></i><span style=\"font-family:Verdana;\">antibacterial
and antifungal effectiveness. Yields of tannins were quantified by </span></span><span lang=\"EN-US\" style=\"font-size:10pt;font-family:Verdana;\">colorimetric assay following methodology described in the
Brazilian Pharmacopoeia and the antimicrobial activity was determined by
