Abstract

The aim of this study was to investigate the protective effect of water soluble polysaccharide from the leaves of Buluh beting (Gigantochloa levis) (WSPBL) on antioxidant activities. The results revealed that the WSPBL of Gigantochloa levis contained 1.15 ± 0.02 % moisture, 1.35 ± 0.01 % ash, 0.08 ± 0.10 % protein and 30.97 ± 0.01 % total sugar content respectively. The aqueous extracts of WSPBL were used to assess antioxidant properties by using Folin-Ciocalteu reagent method (TPC), 2,2-diphenyl-1-picrylhydrazyl method (DPPH assay) and Ferric Reducing Antioxidant Power (FRAP assay). WSPBL of Gigantochloa levis was found to contain high amount of bioactive compounds including total phenolic compounds (1601 ± 0.02 mg GAE/100 g of sample), DPPH and FRAP with values of 97.32 ± 0.03 % and 137.25 ± 0.01 mg/g TEAC respectively.
