Abstract: The micronutrients and antinutrient (minerals and vitamins) contents of oha seed (Pterocarpusmildbreadii), were analyzed using accepted methods after the minerals value of the plant seeds has been grounded and converted to paste.The micronutrients assay revealed the presence of calcium (Ca2+), potassium (K+), copper (Cu2+), iron (Fe2+), magnesium (Mg2+), manganese (Mn2+) and phosphorous (P+) in the seed sample. The highest micro element found was potassium (K+) and least was zinc (Zn2+) with 13926.96 mg/kg and 1.567 mg/kg in Pterocarpusmildbreadii seeds respectively. The results obtained revealed the presence of fat-soluble vitamins D and one water-soluble vitamins B. Vitamin D was found to be 33.28?g/100g while vitamin B1 was 2.92mg/100g. Other quantified antinutrients were phenol, glycosides,saponnin, tannin, terpenes and steroids which ranges from 0.329% to 0.0051%. The result showed that the oha seeds contain appreciable number of micronutrients, vitamins and low level of antinutrients and could contribute to the recommended dietary allowance of the body.
