The antinutrient and micronutrient (minerals and vitamins) contents of processed and raw seeds of “Nturukpa” (Pterocarpus santalinoides), a wild plant in Nigeria were analyzed using accepted methods. The various quantities (in mg/100g sample) of the antinutrients ranging from hydrogen cyanide (11.25±1.46), through alkaloids, saponins, flavonoids, oxalates, tannins, phytic acid to phynols (0.18±0.02) contained in raw “Nturukpa” (Pterocarpus santalinoides) seed powder were reduced by 4.98% (in saponins) to 63.64% (in oxalates) when processed. In mg/100g sample, the micronutrients: P (86.21±16.48), Na (16.07±1.76), Fe (0.68±0.02) and K (0.48±0.12) and, Ascobate (5.87±0.84), B3 (1.32±0.41), and B2 (0.31±0.05) were respectively the most abundant minerals and vitamins in the raw sample. Except for potassium and vitamin D that were not affected by processing, the concentrations of other micronutrients were diversely increased. The processed plant food, relative to the established physiologically tolerable limits for the antinutrients is safe for human consumption and an excellent source of the minerals: Fe, Zn, P, I, Mn, Cu and Se; the B vitamins and Ascobate (vitamin C) as 1kg could supply substantial proportion of the RDA for the nutrients.
