Abstract

The base, stem and leaves of Etlingera brevilabrum were extracted consecutively with hexane, ethyl acetate, acetone, methanol, methanol:water (1:1) and water and also solely with ethanol. The total phenolic content and antioxidant assays of DPPH radical scavenging activity, b-carotene bleaching, ferrous ion chelating ability and reducing power were carried out on the extracts. In most of the assays, the leaf extracts showed more activity than the others. The methanolic extract of leaf showed the highest total phenolic content and inhibition of b-carotene bleaching. The methanol:water extract of the leaf exhibited maximum DPPH radical scavenging and reducing power activity. However, the base methanolic extract showed the highest ferrous ion chelating ability, even higher than the positive controls of ascorbic acid and citric acid. All the extracts gave good linear correlations between total phenolic content and radical scavenging activity as well as between total phenolic content and reducing power.
