KEYWORDS: Cucurbita maxima, Phytochemicals, Proximate analysis, Pumpkin peel.


Pumpkin(Cucurbita maxima) peel was analyzed for its proximate composition and  phytochemical constituents. Various standard techniques were used in the phytochemical and  proximate analyses. The phytochemical screening revealed the presence of tannins, saponins, phlobatannins, flavonoids, terpenoids, steroids, alkaloids, carbohydrates and glycosides. The sample was found to contain all the phytochemicals tested in varying degrees except anthraquinones that was not detected. Results of proximate analysis revealed that moisture, ash, fat, crude fibre, crude protein and carbohydrate contents were 5.20, 6.32, 3.11, 35.97, 11.73, and 37.67% respectively. The presence of bioactive compounds and the result of proximate analysis is an indication that pumpkin peel has medicinal activity, and could also be used as food. Therefore the peel could serve as a source of ingredient to the food and pharmaceutical industries
