Abstract

Maclura tinctoria L. D. Don ex Steud. has one of the highest qualities among the coefficients for Brazilian woods up to 9.6 and resistance rates equivalent to Indian teak Tectona grandis. In this study, the macromolecular constituents and total phenols compounds as well as the antioxidant and antibacterial activities of this wood were evaluated. Total phenols and proanthocyanidin levels were higher in wood when compared with bark levels. The antioxidant activity of wood extracts IC50 = 18.7 μg-mL was more effective than that of bark extracts IC50 = 20.9 μg-mL. Wood and bark extracts revealed a high potential for inhibition of aerobic and anaerobic bacteria. The bark extracts were the most active MIC from 20 to 60 μg-mL. Both antioxidant activity and high potential for bacteria inhibition turn these extracts promising for drug formulations, especially as antibacterial agent.
