Ethanolic extracts of the dry weight leaves and rhizomes of Etlingera pubimarginata (Elmer) A.D.Poulsen were used in this study to determine its phenolic content and antioxidant activity. Total phenolic content was determined using the Folin-Ciocalteu method, while phosphomolybdenum method was used for the total antioxidant activity. Data revealed that the total phenolic content in E. pubimarginata leaves (27.25 ± 0.72 mg GAE/g dried sample) have greater amount of phenolics than its rhizomes (0.76 ± 0.11 mg GAE/g dried sample). Further, total antioxidant activity of E. pubimarginata was observed higher in leaves (34.83 ± 0.49 mg AAE/g dried sample) than rhizomes (1.82 ± 0.09 mg AAE/g dried sample), as well as the reducing power revealed to have higher amounts in the leaves (24.83 ± 2.99 mg GRPE/g dried sample) than the rhizomes (0.33 ± 0.10 mg GRPE/g dried sample). The high contents of phenolic compounds contribute to the antioxidant activity of extracts of E. pubimarginata. A perfect positive linear relationship was observed among the total phenolic content, total antioxidant activity, and reducing power (r=1, p<0.001) based on the correlation analysis. These imply that E. pubimarginata could be potentially used as a new source of natural antioxidant. Furthermore, a description of the species, including its updated distribution, phenology, and habitat and ecology are provided in this paper.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
