The roots of Boesenbergia rotunda are prominent ingredients in the cuisine of several Asian countries, including Thailand, Malaysia, Indonesia, India, and China. Recently, fingerroot (Boesenbergia rotunda) was successfully cultivated in South Korea. In this study, the radical scavenging and α-glucosidase inhibitory activities of Korean fingerroot extracts obtained using different extraction methods (i.e., organic solvent and hot water extractions) were investigated. More specifically, the antioxidant activities were evaluated using the hydroxyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assays, while the anti-diabetic effects of the various solvent extracts of fingerroot were tested using the α-glucosidase inhibitory assay. Among the tested samples the 80% methanolic (MeOH) extract showed the most potent activities, with IC50 values of 82.3±2.3 and 75.0±2.4 μg/mL, respectively for the hydroxyl and ABTS radical scavenging activities. Also, the 80% MeOH extract exhibited the greatest α-glucosidase inhibitory effects, with an IC50 value of 151.6±3.6 μg/mL. Finally, the total phenolic content of 80% MeOH extract was found to be 106.0±1.7 mg equivalent of gallic acid per g of extract. These results suggest that the 80% MeOH extract of fingerroot can be considered as a new effective source of natural antioxidant and anti-diabetic materials.
