Abstract
Electrochemical properties of Aloe emodin in aqueous and nonaqueous solvents of DMSO were studied by cyclic voltammetry and linear sweep voltammetry at a platinum electode.A pairs of currents on the voltammogram may be attributed to a quasi-reversible-one-electron transfer in HAc-NaAc and DMSO,the peak potential in DMSO was found to move more negatively compared with that in HAc-NaAc.A new method for Aloe emodin determination is described.The peak current is proportional to the concentration of Aloe emodin over the ranges of 1.0×10~(-5)~6.0×10~(-4)mol/L.(The electrochemical properties of Aloe emodin were related to solvents.)
