Costus speciosus L. is a tuberous plant commonly available in wetlands and near water bodies throughout Odisha state and used as food and medicinal purposes. The tribal communities of the state used the rhizome to cure joint pain, skin infections and consume as nutraceutical. The above claims are supportive of the fact that the rhizome might have antioxidant potentials and might be rich with diverse secondary metabolites. Keeping this in view an attempt has been made to evaluate the bioactive compounds present in the plant parts and antioxidant potentials in order to validate the tribal claims. Results revealed that the plant parts are rich with phenolic compounds and have antioxidant potential.
