In order to promote consumption of edible mushrooms in Côte d’Ivoire, a chemical study was conducted. The composition of six species of edible mushrooms (Volvariella volvacea, Termitomyces letestui, Psathyrella tuberculata, Lentinus brunneofloccosus, Hirneola auriculajudae, Pleurotus ostreatus) was determined. The results showed that V. volvacea is the richest (P≤0.05) in fat (3.24 ± 0.24 % DM), sodium (67.41 ± 0.01 mg/100 g DM), phosphorus (2137.20 ± 0.10 mg/100 g DM), chlorine (889.13 ± 0.23 mg/100 g DM), flavonoids (3.15 ± 0.03 mg/100 g DM), tannins (17.59 ± 0.09 mg/100 g DM) and oxalates (253.93 ± 1.78 mg/100 g DM). T. letestui has a higher content (P≤0.05) of crude proteins (19.48 ± 0.65 % DM), digestible proteins (13.65 ± 0.46 % DM), ash (21.44 ± 0.34 % DM), magnesium (351.61 ± 0.07 mg/100 g DM), iron (1076.28 ± 0.17 mg/100 g DM) and copper (85.76 ± 0.02 mg/100 g DM). Reducing sugars (740.99 ± 3.94 mg/100 g DM), total sugars (1654.06 ± 0.00 mg DM) and potassium (8042.77 ± 0.31 mg DM) concentrations are greater (P≤0.05) in P. tuberculata. L. brunneofloccosus has a higher content (P≤0.05) of fibers (42.74 ± 0.07 % DM), calcium (337.89 ± 0.05 mg/100 g DM) and zinc (17.30 ± 0.00 mg/100 g DM). The highest content (P≤0.05) of digestible carbohydrates (57.60 ± 0.65 % DM), manganese (4.26 ± 0.00 mg/100 g DM), phytates (109.88 ± 0.13 mg/100 g DM) and a stronger (P≤0.05) anti-radical activity (51.75 ± 0.34 mg/100 g DM) were recorded in H. auriculajudae. P. ostreatus is richer (P≤0.05) in moisture (92.05 ± 0.55 % FM), energy (246.61 ± 1.41 kcal/100 g DM) and polyphenols (112.97 ± 0.28 mg/100 g DM). These results clearly show that mushrooms are rich in nutrients.
