Various scientific studies have reported the presence of steroids, triterpenoids, phenols, flavonoids, alkaloids, and polysaccharide-protein complexes in Pleurotus mushrooms. Various in vitro and in vivo assays have shown antioxidant, antidiabetes, cholesterol-lowering, antimicrobial, anti-inflammatory, and antitumor activities. This study investigated the acetylcholinesterase inhibitory activity (through the use of a spectrophotometric method) and the antioxidant potential (on the basis of DPPH scavenging activity) of hydromethanol extracts of fresh fruiting bodies of 4 Pleurotus species. The extracts of the selected mushrooms exhibited significant correlations between acetylcholinesterase inhibition and antioxidant activity and between total phenol, flavonoid, and alkaloid contents. Among the 4 species, P. florida showed the strongest acetylcholinesterase inhibition (half-maximal inhibitory concentration, 59.13 ± 1.37 mg/mL) and antioxidant activity (half-maximal inhibitory concentration, 239.02 ± 0.22 μg/mL). The findings of this study demonstrate that Pleurotus mushrooms, specifically P. florida, may be considered as a potential source of antioxidant and acetylcholinesterase-inhibitory agents.
