Biological Activities of Ethanol Extracts of Hericium erinaceus Obtained as a Result of Optimization Analysis.

Mushrooms are one of the indispensable elements of human diets. Edible mushrooms stand out with their aroma and nutritional properties. In this study, some biological activities of the wild edible mushroom Hericium erinaceus were determined. In this context, firstly, the most suitable extraction conditions of the fungus in terms of biological activity were determined. First, 64 different experiments were performed with the Soxhlet device under 40-70 °C extraction temperature, 3-9 h extraction time, and 0.5-2 mg/mL extraction conditions. As a result, a total antioxidant status (TAS) analysis was performed, and the extraction conditions were optimized so that the objective function was the maximum TAS value. The data obtained from the experimental study were modeled with artificial neural networks (ANNs), one of the artificial intelligence methods, and optimized with a genetic algorithm (GA). All subsequent tests were performed using the extract obtained under optimum extraction conditions. The antioxidant capacity of the mushroom was assessed using Rel assay kits and the DPPH and FRAP techniques. The agar dilution method was used to measure the antimicrobial activity. The anti-Alzheimer activity was assessed based on the activities of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The antiproliferative activity was assessed against the A549 cancer cell line. The total phenolic content was measured using the Folin-Ciocalteu reagent. The measurement of total flavonoids was conducted using the aluminum chloride test. LC-MS/MS equipment was used to screen for the presence of standard chemicals. The optimum extraction conditions were found to be a 60.667 °C temperature, 7.833 h, and 1.98 mg/mL. It was determined that the mushroom has high antioxidant potential. It was determined that the substance was successful at combating common bacterial and fungal strains when used at dosages ranging from 25 to 200 µg/mL. The high antiproliferative effect of the substance was attributed to its heightened concentration. The anti-AChE value was found to be 13.85 µg/mL, while the anti-BChE value was confirmed to be 28.00 µg/mL. The phenolic analysis of the mushroom revealed the presence of 13 chemicals. This investigation found that H. erinaceus exhibits robust biological activity when extracted under appropriate circumstances.

Mushrooms are among the natural products that are widely used in the treatment of diseases. In our study, the biological activities of Candolleomyces candolleanus (Fr.) D. Wacht. & A. Melzer were determined. Within the scope of the study, ethanol and methanol extracts of the basidiomata of the mushroom were obtained. Total antioxidant, total oxidant, and oxidative stress values of the mushroom were determined using Rel Assay kits. Its antimicrobial activity was tested against standard bacterial and fungal strains by agar dilution method. Antiproliferative activity was measured against A549 lung cancer cell line by MTT assay. Element contents were determined using atomic absorption spectrometry. According to the findings, the TAS value of the mushroom was determined as 5.547 ± 0.173, the TOS value as 8.572 ± 0.217 and the OSI value as 0.155 ± 0.001. It was determined that the mushroom extract was effective at 25-400 µg/mL concentrations. Element contents were determined to be at normal levels. The antiproliferative activity of the extracts showed strong effects depending on the concentration increase. As a result, it was determined that the biological activities of the extracts of C. candolleanus were high.

Antioxidant, Antimicrobial, and Antiproliferative Activities of Wild Mushroom, Laeticutis cristata (Agaricomycetes), from Turkey.

In this study, the antioxidant status, oxidant status, antimicrobial activity, and antiproliferative activity of wild mushroom, Laeticutis cristata, were determined. Total antioxidant status (TAS) and total oxidant status (TOS) were determined using the Rel Assay TAS kit and the Rel Assay TOS kit, respectively. Antibacterial and antifungal activities were determined using the modified agar dilution method. An antiproliferative effect was determined by the MTT cell viability assay against lung cancer cell line A549. L. cristata demonstrated significant antioxidant potential, with a TAS value of 3.623 ± 0.250, TOS of 27.476 ± 0.314, and oxidative stress index of 0.765 ± 0.051. In addition, its antifungal activity was high (25 µg/mL). L. cristata was determined to have a strong antiproliferative effect against A549. As a result, it is thought that L. cristata can be used as a natural material in pharmacological designs.

The total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) were 3.410 ± 0.099 mmol/L, 7.548 ± 0.147 µmol/L and 0.221 ± 0.005 respectively. O. asterosperma showed some promising antimicrobial activity. The extract showed no genotoxic potential and attenuated hydrogen peroxide (H2O2)-induced oxidative DNA damage in neurons. Pre-treatment with O. asterosperma maintained mitochondrial function, reduced expression levels of cleaved-caspase-3 and apoptosis-inducing factor (AIF) when HT22 cells were exposed to pathophysiological concentrations of GLU (25 mM) and modulated protein kinase B (Akt), the mammalian target of rapamycin (mTOR), and the phosphotase and tensin homolog on chromosome ten (PTEN). O. asterosperma is an important food for the treatment or management of neurodegenerative disorders due to its phenolic content and potent antioxidant and anti-excitotoxic effects.
