Fig. 5From: Preparation, structural characterization and in vitro activity of ginger polysaccharideChromatogram of polysaccharide methylation analysis of ginger. After hydrolysis of ginger polysaccharide, under the combined action of electric field and magnetic field of mass analyzer, it was separated according to the size of m/z and then detected and recorded, so as to obtain the characteristic fragments of ginger polysaccharide after methylationBack to article page
