Preparation and inhibition on α- d -glucosidase of low molecular weight polysaccharide from Cordyceps militaris

The structural properties and the inhibition on α-d-glucosidase activity of the low molecular weight (LCMPs-II) obtained from the optimized acid hydrolysis of the Cordyceps militaris polysaccharides (CMPs) were investigated in this paper. The LCMPs-II with a molecular weight of 28 KDa mainly composed of rhamnose, xylose and glucose with the molar ratio of 1: 2.19: 6.73 was separated from LCMPs-I which was the acid hydrolysis product of CMPs by...
