Another low-molecular polysaccharide fraction (K-2-L) obtained from the same extract was composed of a large amount of glucose (ca. 83%) in addition to mannose, 3-O-methylgalactose, and galactose. K-2-L showed a characteristic absorption band at 890 cm^<-1> in the infrared spectrum, suggesting the presence of β-glycosidic linkages. In biological screening tests, K-2-F and K-2-L exhibited mitogenic activity in a dose-dependent manner, and the mitogenic potency of K-2-F was stronger than that of K-2-L. In addition, only K-2-F showed significant colony-stimulating factor-inducing activity.}, pages = {75--82}, title = {カシサルノコシカケ水性エタノール抽出多糖画分の諸性質}, volume = {32}, year = {2000}, yomi = {ハラ, チヒロ} }
