Effect of tannins concentration in the Rhizophora mangle L. aqueous extract and its polyphenolic fraction on DPPH radical generation. The butylated hydroxytoluene (concentration: 22.0 µg/mL, percentage of inhibition: 29.7) and phloroglucinol (concentration: 37.8 µg/mL, percentage of inhibition: 43.1) were used as positive controls. Data are expressed as mean ± standard error of mean of 3 different experiments
