Chemical analysis on Citrullus colocynthis and Irvigna gabonesis seeds was carried out to predict their possible medicinal value and therapeutic applications using standard methods. Analysis of vitamin contents revealed that the seeds were predominantly composed of water soluble vitamins. Vitamin B 1 , B 2 , B 6 and B 12 contributed a total of 610.15mg/100g and 898.66mg/100g in Citrullus colocynthis and Irvigna gabonesis respectively. Vitamin C was high in both seeds with values for Citrullus

The phytochemical composition revealed high concentration of tannins and alkaloids. Some antinutrients such as phytate, cyanogenic glycosides, hemagluttinin, saponins and oxalates were present at very low concentrations. Flavonoids, steroids, terpenoids and phenols were also present at high concentrations while beta carotene occurred at very low concentration of 0.31±0.01 and 0.92±0.01mg/100g for Irvigna gabonesis and Citrullus colocynthis respectively. The high concentration of vitamin C, flavonoids and phenols were indicative of high antioxidant activity. I.
