The almonds of (Irvingia gabonesis) "Siako" in the Betes or "pkle" among the Gueres are used in food of the people of the West of Ivory Coast. The sauce from these almonds is an accompaniment for typical dishes. Unfortunately these spontaneous food plants are less and less present in our markets given the excessive deforestation. In order to valorize these almonds and to encourage the domestication of the plant, we are interested in the determination of the essential constituents of these almond found in our main markets in Daloa (Central-West of Côte d'Ivoire).The results obtained after chemical analysis give nutrient contents respectively: 36,82 ± 0,26; 14,56 ± 0,26; 6, 62 ± 0,71; 13,85 ± 0,16; 13,30±5,20; 10,21±4,20; 12,69 ±3,14 and 21,41 ± 2,5%. In addition, biometric and physiological studies with rats (Wistar) revealed steady weight gain after the sixth day. This weight gain confirms the good quality of this spontaneous food plant. This suggests the popularization of this plant in the dietary practice of our populations and level with the well being of these.
