“…The fruiting bodies are a source of different groups of compounds endowed with valuable biological properties: immunostimulating, antioxidant, anticancer, hypocholesterolemic (Garlaschelli, Pang, Sterner, & Vidari 1994;Wasser, 2002). All four species under analysis are a source of immunostimulating b-glucans (Bush, Wantoch, Rekowski, & Mollken, 2007a, 2007bSułkowska-Ziaja, Muszyń ska, & Koń ska, 2005), chitin and chitosanes (Yang, Lin, & Mau, 2001), and selenium (Zaidman, Yassin, Mahajana, & Wasser, 2005). Moreover, these species contain proteins, lectins, and many enzymes including proteases, ribonucleases, lactase (Liu, 2005;Ng & Wang, 2003).…”
