The wild yam tubers consumed by the tribes Kanikkars / Palliyars of South- Eastern slopes of Western Ghats, Tamil Nadu (Dioscorea alata, D. bulbifera var vera, D. esculenta, D. oppositifolia var dukhumensis, D.oppositifolia var. oppositifolia, D. pentaphylla var. pentaphylla, D. spicata, D. tomentosa and D. wallichi) were evaluated for its nutritional quality. From the present investigation, it is observed that most of the wild edible yams were found to be a good source of protein, lipid, crude fibre, starch, vitamins and minerals. Antinutritional substances like total free phenolics, tannins, hydrogen cyanide, total oxalate, amylase and trypsin inhibitor activities were quantified.
