Curcubita pepo seeds have been widely consumed in Zimbabwe way back in the 1970s, but still locally, there is no data on the nutritional quality of Curcubita pepo seeds, hence the study attempted to avail this information. Curcubita pepo seeds from selected places in Zimbabwe were analysed. The proximate analysis including major nutrients and minerals were determined. The C. pepo seed had a moisture content of 5.662±0.016gkg-1. Significantly, Curcubita pepo had high amounts of crude oil and proteins as compared to other edible oil rich seeds. The crude oil content and protein were 43.460±0.098gkg-1 and 32.860±0.103gkg-1 respectively. Other components such as carbohydrates, crude fibre and energy were 12.160±0.142gkg-1, 2.578±0.007gkg-1 and 562.82±0.132gkg-1 correspondingly. Ash content was 3.324±0.010gkg-1 which was further analysed into various major minerals giving analysed means as Na (67.956±0.037gkg-1), Zn (1.244±0.010gkg-1), P (1040.8±0.663gkg-1), Fe (11.980±0.086gkg-1), Ca (141±0.316gkg-1) and Mg (344.6±0.245gkg-1). The findings indicated that C. pepo seeds are a good alternative source of highly nutritious food for instance proteins and lipids as well as minerals (Mg, Ca, Zn, P and Fe) that could greatly contribute to human nutritional requirements. However, it still remains important to further profile the quality of the lipids and proteins from C. pepo seed so as to verify their essentiality and availability to the human body as well as evaluating the presence of other bioactive and antinutritional factors that might be present in these seeds.
