Tramesan, a novel polysaccharide from Trametes versicolor. Structural characterization and biological effects.
Mushrooms represent a formidable source of bioactive compounds.Some of these may be considered as biological response modifiers; these include compounds with a specific biological function: antibiotics (e.g.plectasin), immune system stimulator (e,g, lentinan), antitumor agents (e.g.krestin, PSK) and hypolipidemic agents (e.g.lovastatin) inter alia.
