In this sudy, the antimicrobial properties of acetone, ethanol, DMSO (dimethylsulfoxide) and water extracts from   <em>L. deliciosus </em> (L.) were evaluated the effect against Gram positive and Gram negative bacteria and fungi. The highest inhibitory activity was determined against <em>P. aeruginosa </em> (30±0.0 mm, zone diameter) with acetone and ethanol extracts. On the other hand, the weakest inhibitory activity was determined against <em>S. aureus </em> and <em>C </em> <em>. albicans </em> (9±0.0 mm, zone diameter) with DMSO and distilled water extract of <em> </em>mushroom. Also, in this study, <em>L. deliciosus </em>(L.) was analyzed for proximate chemical constituents (moisture, fat, protein, ash and dry matter). Moisture, fat, protein, ash and dry matter levels of the mushroom were found as 8.75±0.72, 2.64±0.16, 75.25±0.15, 4.61±0.03, 89.96±0.24% mg/100g respectively. The quantitative estimation of the total phenolic contents and flavonoid quantification of  <em>L. deliciosus </em>were determined by a colorimetric method. The total phenolic content and total flavonoid were found as 4,84±0,32 mg <sub>GAE </sub>/g <sub>extract </sub> and 2,76±0,03 mg/g. The antioxidative activity of the mushroom was elucidated by DPPH free radical scavenging capacity. As a result; DPPH scavenging activity of methanolic mushroom extract was found to be IC <sub>50: </sub> ›17. In this study showed that the <em>L. deliciosus </em>not only in terms of nutritional value is also noteworthy that the therapeutically. <p> <strong> <em>Keywords: </em> </strong> <em>L. deliciosus </em>(L.), antimicrobial, antioxidant, chemical composition </p>}, number={1}, publisher={Kastamonu University}
