Citation abstract

Trametes versicolor is important for its medicinal rather than nutritional value. It has a variety of pharmacological activities. The purpose of this study was to elucidate the bioactive properties of the wild medicinal mushroom T. versicolor (L.) Lloyd. Samples were analyzed for antioxidant potential and the chemical composition of the major bioactive chemical components. Chromatographic procedures were used to analyze phenolic compounds, free amino acids, vitamins, and fatty acids. T. versicolor was analyzed for moisture (87.21 ± 1.08 g/100 g fw), protein (11.07 ± 0.85 g/100 g dw), and fat (1.35 ± 0.09 g/100 g dw) content. Phenolic compounds in T. versicolor were found as p-hydroxy benzoic (113.16 ± 0.22 μg/g dw), protocatechuic (10.07 ± 0.54 μg/g dw), vanillic (5.21 ± 0.10 μg/g dw), and homogentisic acids (1.24 ± 0.15 μg/g dw). In the studied mushroom, essential and nonessential amino acids were determined as leucine (72.41 ± 0.16 mg/100 g dw), isoleucine (60.07 ± 0.10 mg/100 g dw), methionine (53.51 ± 0.09 mg/100 g dw), tyrosine (33.37 ± 0.27 mg/100 g dw), glutamine (15.48 ± 0.19 mg/100 g dw), and asparagine (10.90 ± 0.13 mg/100 g dw). Vitamin content of T. versicolor was found as nicotinic acid (26.52 ± 0.10 mg/100 g dw) and nicotinamide (12.18 ± 0.05 mg/100 g dw). Fatty acids in T. versicolor were linoleic acid (18:2n6c), oleic acid (18:1n9c), palmitic acid (C16:0), stearic acid (C18:0), and linolenic acid (18:3n3). In conclusion, the results of the present study support the potential use of T. versicolor as a promising source of bioactive products for pharmaceutical and also food industries.
