Author(s): Sandhya Ghosh, Mandadi Narsimha Reddy
Abstract: Present study was carried out to assess nutraceutical values of wild edible herb H. auriculata with its antioxidant potentials. Proximate analysis of the moisture, ash and crude fat content reveals 65±1.45%, 0.29±0.17% and 3±1% respectively. H. auriculata ranked highest in crude fibre (4.53±1.22%) and carbohydrate (64.83±1.38%) content. Protein content was observed to be low (8±0.74%). The mineral analysis revealed high amount of calcium (161.28±9.25mg/kg) and potassium (158.83±5.31mg/kg). Phytochemistry of H. auriculata also indicated the presence of alkaloids, flavonoids, phenols, steroids, saponins and cardiac glycosides. The plant contains a very good amount of vitamin C (48.1±2.19 mg/100gm) along with water soluble B vitamins ranged between 0.0133±0.02 to 6.9±0.40 mg/100gm. The plant also showed a good dose dependent antioxidant activity against both DPPH and H2O2 molecules. The outcome of the study indicates that proximate composition, mineral contents, vitamin contents and antioxidant properties of this plant could be used for the nutritional purpose.
