10.22376/ijpbs.2019.10.1.p1-12 Volume 6 Issue 1 2015 (January - March) Amarkand tubers are routinely consumed by Indian tribes as food and medicine. Some species from genus lessThan i greaterThan Eulophia lessThan /i greaterThan (Orchidaceae) and lessThan i greaterThan Dioscorea bulbifera lessThan /i greaterThan L. (Dioscoraceae) are referred as Amarkand. Their different local names and location specific availability lead to ambiguity in identification and incorrect selection of a particular species as medicine. Present study is focused to find out their polyphenolic content and free radical scavenging potential. It was found that tubers and bulbils of lessThan i greaterThan D. bulbifera lessThan /i greaterThan (DBT and DBT) can scavenge 2, 2-diphenyl-1-picrylhydrazyl. Also, they exhibited a better ability to chelate metal ions. lessThan i greaterThan E lessThan /i greaterThan . lessThan i greaterThan leghapanensis lessThan /i greaterThan (EL) could effectively scavenge nitric oxide radical than other species. EL and lessThan i greaterThan E. ochreata lessThan /i greaterThan (EO) showed higher anti-lipid peroxidation potential. Similarly EO demonstrated highest ferric reducing capacity (6.62±0.290 µM Fe (II)/g). Among eight Amarkand species, DBB and tubers of EO, EL, DBT contain high amount of phenols, flavonoids, proanthocynidins and demonstrated considerable antioxidant potential for their use against diseases.  AARTI NARKHEDE AND SURESH JAGTAP Amarkand, Eulophia, Dioscorea, Polyphenolic content, Free radical scavenging potential 1123-1133
