Mode opératoire

In addition to glycerol (2.0 mol) and erythritol (0.14 mol) given in Table 3 above, 2-O-β-D-glucosyl-D-erythritol (0.74 mol) and 2,4-bis-hydroxymethyl-5-O-β-D-glucosyl-1,3-dioxane (0.35 mol) were obtained as the controlled Smith-degradation products of mannoglucan. Furthermore, acetolysis of mannoglucan gave 3-O-α-D-mannosyl-D-glucose and cellobiose, and partial acid hydrolysis of mannoglucan (0.33N sulfuric acid, 100° C., 7 hrs.) yielded 6-O-α-D-mannosyl-D-glucose and cellobiose.
