This allowed for a further purification treatment by the CTAB fractionation process and enabled the separation of acidic and neutral polysaccharides, in accordance with Yang and Zhang’s (2009) research [14].
Yang and Zhang found the separation of an acidic and a neutral polysaccharide is possible using (CTAB), where the outcome will form a precipitated complex with the acidic polysaccharide.
