abstract
Mushroom, a new food item in Bangladesh, has remained largely obscure about its nutritional and medicinal values.rnEvaluation of antioxidant and antimicrobial activity of the Pleurotus florida ethanol extract was the purpose of thernpresent study. Crude P. florida extract was qualitatively screened for the presence of phytochemicals while totalrnpolyphenol content was measured quantitatively. DPPH-free radical scavenging activity, total reducing power andrnability of inhibiting in vitro Fenton’s reagent-induced oxidative stress were used to evaluate the antioxidantrnpotentials of the P. florida extract. Minimum inhibitory concentration and antibiogram of the P. florida extract wasrnassessed against six human pathogenic bacteria. Ethanol extract of P. florida possesses appreciable antioxidantrnactivity, as indicated by the polyphenol contents, DPPH scavenging activity, reducing power and anti-lipid peroxiderneffect. The extract exhibited antimicrobial activity against all of the microorganisms tested.
