A review on biologically active polysaccharides isolation from an edible mushroom, pleurotus Florida and its Assam culture variety

Abstract:
The number of mushrooms on earth is estimated at 140,000, yet maybe only 10% (approximately 14,000 named species) are known. Mushrooms comprise a vast and yet largely untapped source of powerful new pharmaceutical products. In particular, and most importantly for modern medicine, they represent an unlimited source of polysaccharides with antitumor and immuno stimulating properties. Many, Basidiomycetes mushrooms (if not all) contain biologically active polysaccharides in fruit bodies, cultured mycelium, culture broth. Data on mushroom polysaccharides have been collected from 651 species and 7 infra specific texa from 182 genera of higher Hetero-and Homo basidiomycetes. These polysaccharides are of different chemical composition, with most belonging to the group of β-glucans; these have β-(1,3) linkages in the main chain of the glucan and additional β-(1,6) branch points that are needed for their antitumor action. High molecular weight glucans appear to be more effective than those of low molecular weight. Chemical modification is often carried out to improve the antitumor activity of polysaccharides and their clinical qualities (mostly water solubility). Pleurotus species are commonly called oyster mushrooms. There are about 40 species of this mushroom [1] such as Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus citrinopileatus, Pleurotus cornucopiae, Pleurotus tuber-regium, Pleurotus abalones, P. sapidus, P. corticatus, P. columbinus, P. spodoleucus, P. ferulae, P. nebrodensis, P. eryngii, P. pulmonarius, P. tuber-regium, P. cystiodisus, P. djamor, P. salmoneostramineus, and Pleurotus florida etc. They enjoy worldwide distribution, both in temperate and tropical parts of the world. Oyster mushrooms now rank second among the important cultivated mushrooms in the world [1]. The information presented in this review is helpful in exploring and understanding the different mushroom polysaccharides and their biological activities isolation of these edible mushrooms Pleurotus florida and its Assam culture variety from water extract as well as alkali extract.
