Umbilicaria esculentahas been used as a tonic food in China for several centuries owing to its pleasant flavor and health benefits. In this study, a water soluble polysaccharide, which we designated as UP2, with an average molecular weight of 3.33 × 105Da, was isolated fromU.esculentacultivat...
A novel polysaccharide, here named DP1, was isolated from the fruiting body of Dictyophora indusiata using a water extraction method. Structure characterization revealed that DP1 had an average molecular weight of 1132 kDa and consisted of glucose (56.2%), galactose (14.1%), and mannose (29.7%...
The structure of a sulfated polysaccharide isolated from the calcareous red alga Corallina pilulifera was studied by methylation analysis before and after desulfation or Smith degradation, as well as by 1D and 2D 1H and 13C NMR spectroscopy. The polysaccharide was shown to consist of D-galactose...
A polysaccharide-iron complex(PIC), synthesized by the neutralization of an FeCl 3 carbohydrate solution, is marketed as an oral hematinic('Niferex'). The chemistry, structure and solution chemistry of this complex have been examined by a variety of techniques. Elemental analyses are consistent with...
Structure of a polysaccharide from Trichoderma atroviride and its promotion on tanshinones production in Salvia miltiorrhiza hairy roots This study evaluates the chemical structure of a heteropolysaccharide (PSF-W-1) from the endophytic fungus Trichoderma atroviride and its effects on the pr...
