Abstract
Antioxidant activities, antifungal properties and total phenolic compound of
11 selected commercial Malaysian timbers were studied. The species include
Syzygium samarangense (kelat jambu air), Eugenia cerina (kelat gelam), Eugenia
chorantha (kelat merah), Scorodocarpus borneensis (kulim), Myristica cinnamomea
(penarahan arang), Artocarpus elasticus (terap nasi), Pometia pinnata (kasai daun
besar), Palaquium hispidum (nyatoh tembaga kuning), Casuarina equisetifolia (rhu),
Azadirachta indica (neem) and Gonystylus bancanus (ramin melawis). Extract from
bark, sapwood and heartwood of each species were screened for antioxidant using
1,1-diphenyl-2-picrylhydrazyl (DPPH) assay for antioxidant activities, whereas the
total phenolic compound was evaluated using the Folin-Ciocalteu method. The
antifungal activities were observed with Gloephyllum trabeum (brown-rot) and
Pycnoporus sanguineus, which is white-rot. Eugenia cerina (Kelat gelam) bark
showed the highest antioxidant activity while the highest total phenol content was
found in Azadirachta indica (neem) bark.
