Abstract

Trametes species represents a rich source of nutritive compounds with important pharmacological properties like antioxidant, antiinflammatory and anti-cancer properties. However, factors like genetic background, harvesting period, geographic location, climatic conditions and others are influencing the biosynthesis of bioactive compounds, their fingerprint and their concentration. The aim of this study was to determine the antioxidant capacity, total phenolic compounds and total flavonoids content of two mushroom species, namely Tramestes versicolor (TV) and Trametes gibbosa (TG), mushrooms with potential health benefits, harvested from north-west part of Romania. In order to determine the phenolic compounds profile, water, methanol, and acetone mushroom extracts were analyzed using UV-Vis spectroscopy, FTIR spectroscopy and LC-MS analysis. In total 28 compounds were tentatively identified as phenolic acids (11 compounds), flavonols (6 compounds), flavones (6 compounds), coumarins (2 compounds), flavanols, isoflavonoids and biflavonoids (1 compound). The highest antioxidant activity was determined for the methanolic extract while the highest total polyphenols content and total flavonoids content were determined for the water extract. The results obtained suggested that Trametes species can be considered important sources of bioactive compounds, their phenolics composition and content being influenced by a series of factors like geographic area origin and genetic background.

Highlights

Mushrooms have an important nutritional significance mostly because of their valuable chemical composition like high fibre and low-fat content, proteins, vitamins and, minerals all essential in an equilibrated diet (Alispahić et al, 2015; Yahia et al, 2017)
Quantitative analysis Total polyphenol content, total flavonoids content and the antioxidant activity of Trametes versicolor (TV) and Trametes gibbosa (TG) water, methanol and acetone extracts are presented in the table (Table 1)
The results were in accordance with the ones reported by Vamanu and Voica (2017) which investigated total phenolic analysis and antioxidant activity of several mushrooms harvested from the region of Moldova, Romania (Vamanu and Voica, 2017)

Summary

Introduction

Mushrooms have an important nutritional significance mostly because of their valuable chemical composition like high fibre and low-fat content, proteins, vitamins and, minerals all essential in an equilibrated diet (Alispahić et al, 2015; Yahia et al, 2017). Phenolic compounds identified in different mushroom varieties have important antioxidant properties (Cheung and Cheung, 2005; Puttaraju et al, 2006; Barros et al, 2007; Yahia et al, 2017). Trametes versicolor (L.) (TV) known as Turkey tail and Trametes gibbosa (TG) known as Lumpy bracket are widespread lignicolous fungal species with white-rot that grows on different trees like oak and Prunus and, on different conifers like fir or pine trees (Janjušević et al, 2017). Even though it is an inedible species, it was used in Received: 28 Jan 2018.
