This work evaluated the mycochemical and proximate composition analysis of the fruiting body extracts of Cyclocybe cylindracea and Pleurotus cornucopiae in order to determine its nutraceutical and pharmacological potential. Extracts of the two exotic mushroom species were obtained using ethanol. The DPPH radical scavenging activity and total phenolic content of the extract were also investigated. Both C. cylindracea and P. cornucopiae contained essential oil, triterpenes, anthraquinones, tannins, flavonoids, phenols, anthrones, fatty acids, alkaloids, steroids, sugars and coumarins. However, anthraquinones and flavonoids were not found in P. cornucopiae. In addition, C. cylindracea contains crude protein (13.5%), crude fat (1.52%), ash content (12.15%), moisture (10.68%), carbohydrates (62.15%) with 316.28 kcal energy value, and exhibits radical scavenging activity (40%) and total phenolic (41.08 mg GAE/g). On the other hand, P. cornucopiae had crude protein (11.98%), crude fat (1.32%), ash content (6.58%), moisture (9.07%), carbohydrates (71.05%) with 344 kcal energy value, and reveals radical scavenging activity (41.75% ) and total phenolic (39.63 mg GAE/g). Therefore, the two exotic species of mushrooms could be considered as healthy food source with pharmacological benefits.
