Abstract

The electrochemical behavior of Maca adenine on the modified electrode of o-phenylenediamine/β-cyclodextrin/Ag-carbon nanotube was studied by cyclic voltammetry. The results show that the electrode modified by 7mg of carbon nanotubes is the best when the concentration of silver ions is 0.1mg/ml. The electrochemical behavior of adenine was investigated by the modified electrode, and it is found that in the PBS buffer of pH= 7, the electrochemical response of adenine on the modified electrode is good and the oxidation peak is obvious. The oxidation peak current showed a good linear relationship with adenine in the range of 0.2 mg/ml to 1.0 mg/ml , and the determination method of adenine content in maca was established. The method is sensitive, simple and reproducible and can be used to extract the content of adenine in maca accurately.
