dc.description.abstractMushroom is use in the preparation of several delicacies in many part of Nigeria, There is dearths of information on the nutritional qualities of oyster mushroom (Pleurotus sajor caju) cultivated on gmelina wood waste. Hence, this study is designed to ascertain the nutritional composition and phytochemical properties of indigenous wild species of oyster mushroom (Pleurotus sajor caju) and the exotic species that is commercially grown on gmelina wood waste at the Forestry Research Institute in Ibadan, Nigeria. The samples were obtained and analysed for proximate, mineral and phytochemical properties on dry weight basis using standard methods. Results of Proximate analyses of the exotic and wild oyster mushroom samples were: moisture (7.00 and 7.15%), protein (19.30 and 25.24%), crude fat (7.24 and 6.65%), crude fibre (7.47 and 7.05%), total ash (7.13 and 8.25%) and carbohydrate by difference (51.86 and 45.66%) respectively. Qualitative analysis of both samples showed the presence of the following phytochemicals: alkaloid, saponin, tannin, cardiac glycosides and flavonoid. The quantitative analysis of the phytochemical properties of the exotic specie’s showed saponin (4.05%), flavonoid (0.06%) tannin (0.27%) cardiac glycosides (0.63%) and alkaloid (10.05%); while, the wild specie showed saponin (3.03%), flavonoid (0.09%), tannin (0.30%) cardiac glycosides (1.45%) and alkaloid (9.64%). Alkaloid seems to be the most predominant phytochemical in the two mushroom species. The values obtained for the predominant minerals content of the exotic sample were: potassium (mg/100g), magnesium (154.75mg/100g), calcium (142.79 mg/100g) and iron (116.90mg/100g); Most of the values were lower compared with the values of the wild counterpart as follow: potassium (665.89mg/100g), magnesium (162.93mg/100g), calcium (147.23mg/100g) and iron (125.61mg/100g). The other minerals for the exotic species ranged from 68.75mg/100g (manganese) to 0.22mg/100g (molybdenum) while, the wild specie ranged from 72.79mg/100g (manganese) to 0.16mg/100g (molybdenum). This study concluded that oyster mushroom grown on gmelina wood waste favourably compared with the wild counterpart and has potential for use as acceptable human fooden_US
