Dans le sahel, les plantes sauvages font encore l’objet de cueillette par les populations rurales afin de les vendre pour subvenir a leurs besoins et de les integrer dans leur alimentation. Les methodes chimiques ont ete utilisees pour la determination de la valeur nutritive de ces fruits. Il ressort que les fruits secs ont les teneurs les plus elevees en sucres (les fruits de Hyphaene thebaica Mart. : 59,78 ±0,14) et en proteine (les fruits de  Parkia biglobosa (Jacq.) Benth. : 6,89%±0,15). Il n’y a pas une grande variation de la teneur en lipides entre les fruits secs et frais. L’analyse des vitamines et mineraux pour 100 g de matieres seches montrent que les fruits de Parkia biglobosa (Jacq) Benth. sont aussi les plus riches en vitamine C (208,71 mg±0,19) et en zinc (47,65 mg±0,16). Les fruits de Tamarindus indica L. ont les teneurs les plus elevees en calcium (183,25 mg±1,45) et les fruits de Balanites aegyptiaca (L.) Del. ont les teneurs les plus elevees en magnesium et en fer (respectivement 201,24 mg±1,91 et 271,98 mg±2,99). Ces resultats montrent que les fruits sauvages sont une bonne source de nutriments et par consequent, ils peuvent faire l’objet de valorisation aupres des populations rurales. © 2015 International Formulae Group.

Chemical methods were used for the determination of the nutritional value of these fruits. It appears that dried fruits had the highest carbohydrate (the fruits of Hyphaene thebaica Mart.: 59.78% ±0.14) and protein (the fruits of Parkia biglobosa (Jacq.) Benth: 6.89%±0.15) contents. There was no significant variation in the fat content between dry and fresh fruits. The analysis of vitamins and minerals for 100 g of dry matter showed that the fruits of Parkia biglobosa (Jacq) Benth. are also the richest in vitamin C (208.71 mg±0.19) and zinc (47.65 mg±0.16). The fruits of Tamarindus indica L. had the highest level of calcium (183.25 mg±1.45) and the fruits of Balanites aegyptiaca (L) Del. had the highest magnesium and iron levels (respectively 201.24 mg±1.91 and 271.98 mg±2.99). These results show that wild fruits are a good source of nutrients, and therefore they are subject to valuation with rural populations. © 2015 International Formulae Group. All rights reserved.
