This study aims to contribute to the valuation of unconventional wild oilseeds, by characterizing certain nutritional parameters of the seeds and liquid fat contents of P. macrophylla and T. heckelii, from the flora biodiversity of Côte d'Ivoire.P. macrophylla seeds have a moisture content of 11.9% with 2% ash and 2% dietary fibre while T. heckelii contains 7.5% moisture, 3.33% ash and 3.2% dietary fibre. The mineral analysis of the seeds reveals the strong predominance of minerals potassium (K) and phosphorus (P). The seeds of P. macrophylla contain 1295 mg/100g DM (dry matter) of K and 1141mg/100g DM of P. The respective contents of these two macroelements in T. heckelii are 554.6 and 450.7 mg/100g DM. Analysis revealed that P. macrophylla seeds are richer in trace elements (8.37 mg/100g DM of Fe, 5.18 mg/100g DM of Zn and 2.64 mg/100g DM of Mn) compared to T. heckelii (4.38 mg/100g DM of Fe; 1.45 mg/100g DM of Zn and 1.35 mg/100g DM of Mn). The liquid fat content was 57.7% and 64.7% respectively for P. macrophylla and T. heckelii. P. macrophylla oils have a density of 0.86, a refractive index of 1.51 and a viscosity of 0.55 mPas. As for T. heckelii, it was found a density of 0.84, a refractive index of 1.46 and a viscosity of 0.61 m2/S.
