[email protected]. Received 20 April 2018; Accepted 17 May, 2018 Large varieties of the pumpkin family such as watermelon seed oil detected in the sample using n-hexane and ethanol solvent. There have been previously explored for their medicinal conventions are major elements such as Zn (4.8 mg/100g), Ca (27.0 mg/100g) due to the presence of bioactive metabolites such as cucurbitacin, and Mg (29.8 mg/100g). Furthermore, the proximate analysis triterpenes, sterols, alkaloids, vitamins and minerals, but none of shows that there are presence of crude protein (19.43±0.38%), these products have gained utilization on industrial scale. This ash (5.03±0.05%) crude fibre (26.10±0.03%), crude lipid research is to verify the ongoing experimental and biological (21.54±0.2%), moisture (10.92±0.02%) and carbohydrate analysis to corroborate its ethno-medicinal utilization. It centers (16.98%) respectively. Although there have been significant on the investigation of the phytochemical composition and nutritional value in the seed which is the parts always subverted nutritional bioassay of the indigenous watermelon (Citrullus on the basis of acclaimed toxicity, these in turns can be lanatus ) seed oil sold in Gwagwalada market, Gwagwalada Abuja recommended on daily allowance, maintenance of good district Nigeria (Longitude 8°N and 7°E).
