Antioxidant Activity and Element Content of Suillus collinitus

Abstract

Mushrooms used as food have medicinal importance due to their antioxidant compounds. In this context, it is very important to determine the biological potential of fungi and to reveal these medicinal properties. In this study, it was aimed to determine the element contents, total antioxidant status, total oxidant status, oxidative stress index of Suillus collinitus (Fr.) Kuntze mushroom. In this context, the mushroom samples were extracted with ethanol in the Soxhlet extractor. Element contents were determined using atomic absorption spectrometry. Total antioxidant (TAS) and total oxidant (TOS) levels and oxidative stress index (OSI) were determined using Rel Assay commercial kits. As a result of the study, it was determined that the TAS value of S. collinitus was 2.467 ± 0.145 mmol/L, TOS value was 17.845 ± 0.273 µmol/L and OSI value was 0.677 ± 0.030. In addition, the Fe content (350.72 ± 10.23), Cu content (68.11 ± 2.51), Pb content (11.58 ± 2.43), Zn content (10.46 ± 1.28) and Ni content (1.47 ± 0.21 mg.kg-1) of S. collinitus measured. As a result, S. collinitus mushroom is thought to be a natural source of antioxidants. It has also been observed that the element contents are at normal levels.
