A new electrochemical method for the determination of aloe polysaccharide based on its interaction with alizarin red s was established on a pretreated glassy carbon electrode in pH 3.5 Britton–Robinson buffer solution by linear sweep voltammetry in this work. The decrease of the second order derivative linear sweep voltammetric reductive peak current of alizarin red s is in proportion to aloe polysaccharide...
