Solution properties of an α-(1→3)-d-glucan from Lentinus edodes and its sulfated derivatives

Production and Characterization of Exopolysaccharides from an Enthomopathogenic Fungus Cordycepsmilitaris NG3

“…For rigid rods, their corresponding value of slope is unity (29,40). It should be noted here that most real coils of biopolymers are frequently slightly more extended, changing the slopes from 0.5 to 0.55-0.6 in a good solvent (29,39). Figure 7A-D shows the overall slopes for each EPS in the double logarithmic plots of RMS radius versus molecular weights.…”

“…To the best of our knowledge, there is only one report in the literature concerning analysis of polysaccharides of mushroom origin. Zhang et al (39) analyzed many molecular properties of glucan obtained from the fruiting body of Lentinus edodes using the MALLS system, including absolute molecular weight, intrinsic viscosity, and molecular conformation.…”

Structural analysis of water-soluble glucans from the root of Angelica sinensis (Oliv.) Diels

“…5) NMR experiments, and with reference to previous reports. [14][15][16][17][18][19]22 The carbon signal at d 65.7 ppm should be C-6 of the (1!6)-D D-Glcp, which was shifted about 4 ppm downfield compared with the resonance of standard methyl glycoside due to the effect of glycosylation. 20 Similarly, the C-4 signal at d 76.9 ppm of (1!4)-D D-Glcp appeared at 5.80 ppm downfield compared with that of the standard methyl glycoside.…”

Antitumor Activities ofO-Sulfonated Derivatives of (1→3)-α-D-Glucan from DifferentLentinus edodes

“…3)--Dglucan from Lentinus edodes have been studied in our laboratory, indicating stiffer chains than the native glucan. 11) In this study, we attempted to investigate the antitumor activities of the four water-insoluble (1 ! 3)--D-glucans with different molecular weight isolated from four kinds of fruiting bodies of Lentinus edodes and their water-soluble sulfated derivatives.…”
