Abstract:
The present study aimed to investigate the nutritional properties and antioxidant activities of six underutilized wild edible plants viz. Ipomoea aquatica, Achyranthes aspera, Aasystasia ganjetica, Enhydra fluctuans, Oldenlandia corymbosa and Amaranthus viridis that are commonly consumed as food in the India The antioxidant properties of the plants were evaluated by using 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity, ABTS radical scavenging ability, reducing power capacity, metal chelating activity, lipid peroxidation assay, estimation of total phenolic content and flavonoids content in different solvent extraction system like benzene, chloroform, methanol and 70% aqueous (aq.) ethanol. The quantitation of phenolic acids and flavonoids and water soluble vitamins in these plants were carried out by HPLC using Acclaim C 18 column (5 μm particle size, 250 × 4.6 mm), Dionex Ultimate 3000 liquid chromatograph and detection was carried out in photo diode array (PDA) detector. The results of investigation showed that these plants are rich sources of protein, carbohydrate minerals and vitamins, especially the B group of vitamins that can contribute immensely to nutrition, food security, and health and therapeutic benefits. The different levels of antioxidant activities were found in the solvent systems used. The HPLC analysis also showed the presence of phenolic acids and flavonoids in various amounts in these plants which could be utilized as natural antioxidant.
