ABSTRACT
In this study, we report the anti oxidative potential of the methanolic extract of endemic palm Arenga wightii Griff. By various antioxidant assays including DPPH (2, 2-Diphenyl-1-picrylhydrazyl), ABTS (2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid), nitric oxide, lipid peroxidation and reducing power activity. Fruits exhibited high reduction capability and powerful free radical scavenging ability compared to leaf extract in all the antioxidant assays except ABTS assay. Total phenolics and flavonoid content of plant extract was also determined by a colorimetric method and have significant amounts of phenolics and flavonoids which are responsible for strong antioxidant and anti bacterial activities. The antibiotic activity of both fruit and leaf extract was more pronounced against Staphylococcus aureus. RP-HPLC analysis revealed the presence of major phenolic compounds like gallic acid, ascorbic acid, chlorogenic acid and caffeine in the leaf extract. GC-MS analysis was done for identification of chemical compounds after silylation. Based on the results, we suggest that A. wightii possess high phenolics and other phyto compounds which exhibit effective antioxidant and antibacterial properties.
