Investigation of Nutritional Content, Antioxidant Anticancer and Antimicrobial Activities of Pleurotus eryngii (DC. Ex Fr.) Quel, Extract Obtained by Different Solvents

Abstract

The present study related the nutritional contents, fatty acid compositions, in vitro antioxidant, anticancer and antimicrobial activities of different solvents extracts of Pleurotus eryngii. The nutritional contents of the P. eryngii were investigated in detail. Crude protein (g 100 kg-1), carbohydrate (g 100 kg-1), lipid (g 100 kg-1), ash (g 100 kg-1), dietary fiber (g 100 kg-1) and energy value (cal 100 g-1) of fruiting bodies were analysed. Fatty acid compositions of total lipid, phospholipid and triacylglycerol fractions of Pleurotus eryngii were investigated by Gas chromatography. Totally 13 different fatty acids constituents were identified. Antioxidant properties including total antioxidant activity, free radical scavenging activity, reducing power activity, metal chelating activity, and superoxide anion radical scavenging activity were evaluated using different tests. The highest total antioxidant, DPPH scavenging, metal chelating, and superoxide anion radical scavenging activities were determined in ethyl acetate extracts. The potential of cytotoxic activity on PC-3 (prostate cancer) cell lines was found to depend on the concentration and the type of the tested extracts fractions. It was determined that hexane, ethyl acetate, and methanol extracts of Pleurotus eryngii have inhibition effect on the growth of tested microorganisms. The present results suggested that used as a daily nutrient, the Pleurotus eryngii could be a novel source for new drug developments and promising in some cancer treatment.
