Chemical structure of a novel heteroglycan polysaccharide isolated from the biomass of Ophiocordyceps Sobolifera

This study aims at identifying the structure of polysaccharide (PS) extracted from the biomass of Vietnam-grown Ophiocordyceps sobolifera for the first time. The molecular weight of the obtained polysaccharide (denoted as PS-T100) is found to be 2.29 × 105 Da using gel permeation high-performance liquid chromatography. The structural investigations of the sample PS-T100 unveil a novel structure composed of a heteropolysaccharide with the...
