摘要：

The chemical study of ethanol extract of sapwood of Vatairea guianensis Aubl. resulted in the isolation and structural identification of two compounds not previously described in the literature for the species, namely bolusanthol D and formononetin. In addition, other common compounds were identified, such as physcion, chrysophanol, betulinic acid, sitosterol and stigmasterol. The structural elucidation of substances was performed by spectroscopic data of H-1 and C-13 NMR and bidimensional techniques and comparison with the literature data. The ethanol extract of sapwood showed a significant antioxidant activity (EC50 = 3.7 +/- 0.3 mu g mL(-1)) by DPPH radical scavenging method in comparison to Trolox (EC50 = 4.5 +/- 0.1 mu g mL(-1)). This work is the first describing on chemical studies and antioxidant potential of the sapwood to V. guianensis.
