Özet
Tricholoma is one of the famous genera of Basidiomycota division. Although some species of this genus have been used as culinary mushrooms, very negligible investigations have been conducted on Tricholoma genus phenolic contents and their biological activities. In the present study, the antioxidant, antimicrobial, and DNA protection properties of total phenolic contents of Tricholoma virgatum (Fr.) P. Kumm. (54% methanolic extract) were assessed. T. virgatum phenolic content was determined by an analytic high-performance liquid chromatography (HPLC) method based on compression with standard phenolic compounds including gallic acid, catechin, chlorogenic acid, epicatechin, and coumaric acid. Total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were determined using Rel Assay kits. For DNA protective potential assay, pBR322 supercoiled DNA method was used. The antimicrobial activity assay was done based on the agar dilution method on six different microorganisms include Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Candida tropicalis. The total phenolic contents of this mushroom lied within range of 2.02-56.85 ppm based on coumaric acid and chlorogenic acid as standards. TAS, TOS, and OSI values were determined as 3.754 +/- 0.088 mmol/L, 8.362 +/- 0.085 mu mol/L, and 0.223 +/- 0.007, respectively. T. virgatum methanol extract could exhibit a protective effect on DNA against the hydroxyl radical at 100 mu g/mL concentration. Although T. virgatum is not recommended as an edible mushroom, according to our results, this mushroom could be considered as valuable source for phenolic compounds with significant antioxidant/antimicrobial effects.
