The starches extracted from the tuber of some wild yam species (D, praehensilis, D hirtiflora. D.bulbifera (bulbil and tuber) D. multifera, D burkilliana, D. dumetorum and D. togoensis) picked in the Ivory Coast forest zone, have been studied according to their functional properties which included: iodine absorption spectrum, viscosity, swelling and solubility, syneresis and clarity. These studies showed a wide variety of starches from one species to another at the morphological level.
