    Abstract:

    Objective: Construction of a simple and rapid method for the analysis of ganoderic acid A (GAA). Methods: The molecular imprinted polymer (MIP) that can specifically recognize ganoderic acid A (GAA) were prepared by cyclic voltammetric deposition using GAA as template molecule and o-phenylenediamine as functional monomer. The structure, morphology and electrochemical behavior of MIP were characterized by infrared spectroscopy, scanning electron microscopy and electrochemical methods. Using [Fe(CN)6]3-/4- as the active indicator, the analytical performance of the sensor for GAA was investigated. Porous MIP for GAA can be prepared on the electrode surface by one-step electropolymerization. Results: The results of quantitative analysis showed that the electrochemical signal of [Fe(CN)6]3-/4- had a good linear relationship with the logarithm of GAA concentration in the range of 1.0 pmol/L~1.0 μmol/L, and the detection limit was 0.21 pmol/L. The measured values of GAA in ethanol and water-soluble solution of Ganoderma lucidum powder were 1.15 nmol/L and 3.00 pmol/L, respectively. Conclusion: The MIP-based GAA electrochemical sensor can be used for the rapid determination of GAA in extract solution of Ganoderma lucidum powder.
