چکیده :

More than 130 medicinal functions are thought to be produced by medicinal mushrooms including antitumor, immunomodulating, antioxidant, radical scavenging, cardiovascular, antihypercholesterolemic, antiviral, antibacterial, antiparasitic, antifungal, detoxification, hepatoprotective, antidiabetic, and other effects (1). Extracts of Laetiporus sulphureus were shown to have antimicrobial activity against all fungal strains tested including Candida albicans, Geotrichum candidum, Aspergillus fumigatus, Aspergillus niger, Curvularia clavata, and Fusarium oxysporum, as well as strains of gram-positive (Staphylococcus aureus and Streptococcus pyogenes) and gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Shigella enterica) (2). Numerous bioactive polysaccharides or polysaccharide-protein complexes from mushrooms seem to enhance innate and cell-mediated immune responses, and they exhibit antitumor activities in animals and humans. In mushrooms, unsaturated fatty acids are found to be predominant over saturated fatty acids especially palmitic acid, oleic acid and linoleic acid, while the proportion of linolenic fatty acids is very limited. Mushrooms rich in fat soluble vitamins along with ergosterol content are thought to be the only vegetarian source for vitamin D (3).
