Composition en vitamines et en minéraux des graines de Pterocarpus santalinoides L'Hér. ex De. (Papilionoideae), une plante alimentaire et médicinale de l'Afrique de l'Ouest

Abstract

Vitamins and Minerals Composition in Pterocarpus santalinoides L'Hér. ex De (Papilionoideae) Seeds: a Food and Medicinal Plant of West Africa. Studies were undertaken in order to contribute to the reduction of deficiencies in vitamins and minerals through the use of natural resources.Vitamins and micronutrients compositions of raw or cooked seeds of P. santalinoides L'Hér. ex De. (Papilionoideae), morphotypes 1 and 2 were determined by standardized methods AFNOR and AOAC. In the dry matter, the pro vitamin A content levels ranged from 7 to 100 µg/g and those of vitamin C from 40.103to 155.103 µg/g. The mean levels of total ash, magnesium, potassium, phosphorus, sodium, calcium, iron and chloride in the dry materials were respectively 3.54%; 0.12%; 0.68% ; 0.26% ; 0.06% ; 0.07% ; 0.05% ; 0.42%. Cooking caused vitamin reductions. Raw and cooked seeds can contribute to improve pro vitamin A and vitamin C intake. The results of this study show the relevance of valorizing of Pterocarpus santalinoide.
