Purification and identification of HPW. A Elution curves of crude polysaccharides and the position of HPW. The abscissa is the number of elution tubes, and the ordinate is the absorbance value of the tracking sugar levels at 490 nm by the phenol–sulfuric acid method. B Ion chromatogram of the monosaccharide composition of HPW samples. The abscissa is the retention time (Time, min), and the ordinate is the response value of the ion detection (Response, nC). C Aggregated table of properties and monosaccharide composition of HPW
