Abstract
Vegetables are very important sources of protein and minerals. Some of them even have medicinal properties recognized traditionally. Despite the large number of studies carried out on various vegetables and vegetable crops, very few have scientifically explored the usefulness of S. macrocarpon . This study identified the main groups of chemicals and mineral elements to explain any medicinal or nutritional value. It has also identified some toxic elements contained in this vegetable. Phytochemical screening was carried out on the leaves and fruits of S. macrocarpon . Some mineral elements were determined by Atomic Absorption Spectrophotometry (sodium, potassium, calcium, magnesium) while protein, phosphorous, iron, copper, zinc and toxic metals (lead, cadmium) were determined by Molecular Absorption Spectrophotometry. Fat, ash, moisture and vitamins were sought. The study showed that the leaves of S. macrocarpon were more nutritious than fruits (P < 0.05). The high protein content of the leaves and fruit suggests an interesting nutritive property. The presence of chemical groups and toxic elements (lead, cadmium) in S. macrocarpon require that the consumption of vegetables should be as varied as possible and that the fruit may be consumed with caution. In addition, constraints about vegetable cultivation in Cotonou could lead to research findings that could help provide techniques for producing healthy vegetables.Vitamins A and K1 were found in both parts of this vegetable very rich in water while vitamin E has not been detected. S. macrocarpon also contains lipids at various levels.
