| Abstract: | Myracrodruon urundeuva heartwood is resistant to biodeterioration and lectin purified from heartwood showed antifungal and termiticidal activities. This report deals with antioxidant, antifungal and termite repellent activities of secondary metabolites from M. urundeuva heartwood. Saline (SE, active hemagglutinin preparation) and methanolic (ME, without hemagglutinating activity) extracts contain phenolic compounds, gallic acid, flavonoids, luteolin, cinamic derivatives, proanthocyanidins, hydrolysable tannins, and leucoanthocyanidins. Both SE and ME showed antioxidant activity and were effective in Fusarium growth inhibition. SE was efficient against Fusarium decemcellulare, Fusarium moniliforme, Fusarium oxysporum, and Fusarium solani but it had little effect against Fusarium lateritium. ME practically had no effect on F. decemcellulare and was more active than SE against F. lateritium. SE induced mortality of Nasutitermes corniger (LC50 of 1.81 mg ml?1 for soldiers and 2.59 mg ml?1 for workers) and had no repellent activity. ME had no termiticidal activity but was a good repellent. The detected bioactivities point out the possibility of participation of secondary metabolites in the resistance of M. urundeuva heartwood to biodeterioration. Additionally, the results indicate the use of wood residues, as extracts, a source of natural bioactive agents. |
