Globba marantina is a herbaceous, perennial plant with erect, unbranched stems up to 50cm tall. The plant is harvested from the wild for local use as a food and medicine. The plant used to cure earache and as eye drop to cure conjunctivitis. The small bulbils are used to stimulate the appetite. So, the present study is designed to investigate the possible chemical groups, total phenolic content and antioxidant activities of the crude methanolic extracts of Globba marantina leaves belonging to the family Zingiberaceae. The investigation revealed the presence of alkaloid, cardiac glycosides & steroids. Three complementary test systems, namely total phenolic content, total flavonoid content and total flavonol content were used for the analysis of quantitative determination of phenolic compounds. The presence of high phenolic, flavonoid and flavonol content in the extracts have contributed directly to the antioxidant activity. The antioxidant ability and radical scavenging properties of plants were also measured using three different assays, namely DPPH, RPA and FRAP. The leaves extract also exhibited remarkable antioxidant potentials as compared to the reference standard- ascorbic acid (AA) and butylated hydroxytoluene (BHT). Based on the results obtained in this study, the G. marantina leaves are the most effective antioxidants as determined through different in vitro assays which could be a potential source of natural antioxidants for use in food, cosmetics and pharmaceuticals industries.
