INTRODUCTION
Mushrooms have been a part of human diet in many regions of the world for centuries due to organoleptic characteristic as well as the nutritional values (Wang and Xu, 2014). In nature, there are over 150 000 different types of mushrooms but only 10% is known and designated (Wasser, 2010). However, only about 2 000 species are grown and cultivated for nutritional purposes. The consumption of the mushrooms has even increased remarkably over the past few decades (Gan et al., 2013). Mushrooms are tasteful food, full of proteins, rich in vitamin B, rich in different minerals and have almost all essential amino acids (Mujić et al., 2011). Examination of antioxidant activity in mushroom extracts and content of antioxidant compounds is currently very interesting aim of research.. Mushrooms are found to be rich source of these antioxidants with immense antiradical activity (Valentão et al., 2005).
