dc.description.abstractAntioxidant and antifungal activities of eleven hardwood species of Malaysian commercial timbers from seven families were studied. Methanolic extracts from bark, heartwood and sapwood of each species were subjected to 1,1’-diphenyl-2-picrylhydrazyl (DPPH) for the antioxidant activity determination. Total phenolics were evaluated using the Folin-Ciocalteau method. The tested extracts of Angsana bark, Keruing latek bark and sapwood, all three parts of Kekatong, Merpauh periang bark, Bintangor bukit bark and sapwood, and Sentul bark did showed antioxidant activity. Bintangor bukit bark was further fractionated by column chromatography (CC) and liquid-liquid (partition) chromatography (LLC). Catechol with a few other compounds such as phenol, syringol, guaiacol and 4-methylcatechol were detected by pyrolysis gas chromatography mass spectrometry (Py-GC/MS) as the most important compounds responsible for Bintangor bukit bark to scavenge the free radicals.en_US
