DETERMINATION OF ANTIOXIDANT PROPERTIES OF AGARICUS CAMPESTRIS, PLEUROTUS ERYNGII AND LACTARIUS DELICIOSUS

Agaricus campestris, Pleurotus eryngii and Lactarius deliciosus are species of fungi that naturally grow in the Thrace region. Mushrooms have been used for food and medical purposes for centuries. In this study, the DPPH scavenging activity, the total phenolic substance contents and the reducing power capacities on the methanol and acetone extracts of the mushroom samples were studied. When the DPPH radical scavenging activities are taken into account, the activity is increased depending on the concentration. The highest scavenging activity was found in the acetone extract of P. eryngii with 39.86 ± 2.07 %. It was determined that the total phenolic substances in acetone and methanol extracts of mushroom samples varied between 23,25 ± 0,35-28 ± 0,7 μg GAE / mg extract. The sample showing the highest reducing power capacity was an acetone extract of P. eryngii with a concentration of 0,400 ± 0,021 μg/mL at a concentration of 1000 μg/mL followed by the methanol extract of P. eryngii (0.259 ± 0.030) and the acetone extract of L. deliciosus (0.143 ± 0.010)
