Antioxidant activity of heartwood extracts of Papua New Guinean woods
Journal of Wood Science volume 48, pages 446–450 (2002)
Abstract
Antioxidant effects of methanol extracts from the heartwood of 23 Papua New Guinea (PNG) wood species were examined. The extract ofAmoora sp. (Meliaceae) showed the strongest antioxidant activity against lipid peroxidation in rabbit erythrocyte membrane and linoleic acid autoxidation. Also, the extract ofAmoora sp. showed potent 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicalscavenging activity. These results showed that the heartwood ofAmoora sp. is a possible source of antioxidative agents. The result of antioxidant activity-guided fractionation suggested that gallic acid, protocatechuic acid, and hydrolyzable tannins in the extract ofAmoora sp. caused the potent antioxidant activity.
