METHOD FOR ACQUISITION OF MUSHROOM-DERIVED amp;beta;-GLUCAN POLYSACCHARIDE AND MUSHROOM-DERIVED BETA-GLUCAN POLYSACCHARIDE

摘要

PROBLEM TO BE SOLVED: To provide a new method for selective extraction and fractionation of β-glucans having structures such as β-(1→3)glucan and β-(1→6)glucan being focused attention as physiologically active polysaccharides such as antitumor activity and resultant novel β-glucan polysaccharides.;SOLUTION: One or more β-glucan polysaccharides are extracted and fractionated by weakening or destructing hydrogen bonding in cell walls of basidiomycetes Aphyllophorales mushrooms followed by extraction under a strong alkaline condition.;COPYRIGHT: (C)2005,JPO&NCIPI
