The most important objective of this study was to estimate the nutritional contents like total carbohydrate, lipids, protein, fiber, phenol, flavonoids and moisture content and to evaluate the properties of antioxidant activity. The content of total phenols in the extract was determined spectrometrically according to the Folin-Ciocalteu procedure and calculated as gallic acid equivalent. The achievable antioxidant activity of 2,2-diphenylpicryl-1-picryl-hydrazyl (DPPH) radical scavenging, 2,2’azinobis (3ethyl-benzothiozoline-6-sulphonic acid) disodium salt (ABTS·+) assay, ferric reducing antioxidant power (FRAP) assay, metal chelating activity, superoxide radical scavenging activity was investigated and the result suggested that this freshly harvested plant tubers have more nutritionally potential constituent and antioxidant ability to restore the cell wall damage, mortify and malnutrition.
