10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 3 2013 (July - September) The present investigation scientifically examined the phytochemistry and antibacterial potencies of ethanolic extracts of lessThan i greaterThan Pleurotus lessThan /i greaterThan lessThan i greaterThan florida lessThan /i greaterThan and lessThan i greaterThan Pleurotus ostreatus lessThan /i greaterThan . Phytochemical analyses of the ethanolic extracts of the above pleurotus species revealed that there was moderate levels of terpenoids, tannins, steroidal glycosides and carbohydrates, flavonoids while alkaloids, carboxylic acids, Volatile oils, Cardinolides, Resins, Quinones, fatty acids and cynogenic glycosides were not detected. Generally, both extracts were effective against the isolates tested by agar well diffusion method, respectively. However, ethanolic extract of lessThan i greaterThan P.florida lessThan /i greaterThan exhibited greater antibacterial activity than that of lessThan i greaterThan P.ostreatus lessThan /i greaterThan and further produced growth inhibition of these isolates in broth. The results indicate that lessThan i greaterThan P. florida lessThan /i greaterThan possesses antibacterial activity lessThan i greaterThan . lessThan /i greaterThan SRIDEVI .NEELAM AND SUMMER SINGH Pleurotus florida, Pleurotus ostreatus, organic extracts, antibacterial activity, photochemistry. 396-400
