Abstract: The present study designed to evaluate the proximate composition, minerals content and in vitro antioxidant properties, of the tuber of Dioscorea alata. The quantitation of polyphenolics and water-soluble vitamins in the plant were carried out by High Performance liquid chromatography (HPLC) method. The HPLC analysis were carried out using Dionex Ultimate 3000 liquid chromatograph attached with Acclaim C 18 column (5 μm particle size, 250 x 4.6 mm), and photo diode array (PDA) detector. The toxic heavy metals such as lead, cadmium, arsenic and mercury of the plant were also estimated. The present study showed the presence of very good amount of protein (18.653±0.035%), carbohydrate (43.13±0.031%) and various amount of minerals and heavy metals. The total phenolic and flavonoid content were found 63.846 ± 1.83 mg/gm and 8.213 mg/gm dry extract (DE) respectively in the plant. The plant showed the presence of water- soluble vitamins ranged between 0.004 to 1.548 mg/100gm dry plant material (DPM). The HPLC analysis also indicated the presence of phenolic acids and polyphenolics in various amounts in this wild edible plant. The abundance of protein, fat, carbohydrate, minerals, water soluble vitamins and natural antioxidant components in this plant makes them as considerable sources of nutrition and could be consumed as a regular diet to the human being.
