ABSTRACT
A polysaccharide, named as cordysinan, extracted from natural Cordyceps sinensis, was identified as a hyperbranched heteropolysaccharide from the results of FT-IR, GC-MS, and carbohydrate analysis by carbohydrate gel electrophoresis analysis, as well as the degree of branching of cordysinan was 43.3%. The solution properties of cordysinan were investigated by using size exclusion chromatography coupled with multi-angle laser light scattering and triple detector array, respectively. The molecular weights, the radius of gyration and the intrinsic viscosity of cordysinan were determined as 22.45±0.26 kDa and 22.37 kDa, 15.4±2.4 nm and 1.41 mL/g, respectively. By applying the polymer solution theory, the exponent (ν and α) values of Palabras clave
