Eighteen wild under-utilized crop-seeds were investigated for their tannin, phytin and oxalate contents. Tannic acid content ranged between 0.11% in Coula edulis and 1.15% in Lophira alata. Phytic acid content varied between 330 mg/100 g dry matter in Carapa procera and 1580 mg/100 g dry matter in Terminalia catappa. Total oxalate content ranged between 5.34 g/100 g dry matter in Xylopia aethiopica and 14.0 mg/100 g dry matter in Carapa procera. When soluble oxalate was expressed as a percentage of total oxalate, high values were obtained in Vitex doniana (92.21%) and Xylopia aethiopica (82.0%). The antinutritional effects of these components are discussed in relation to (a) their potentials as feed for livestock and (b) their use as spices, condiments and food supplements by the large rural population in Nigeria.
