The results presented in this thesis show that electrochemical analysis have been successfully carried out on raw plant material of Adansonia digitata fruit. All the four components of the A. digitata fruit, i.e the greenish hairy outer covering, the woody covering, the inner white pulp and the seed have redox active moieties and gave clearly defined cyclic voltametric responses when studied using bare carbon working electrode. They all displayed oxidation/reduction peaks at various potentials. The results show that both hydrolic and sulphuric acid electrolyte media are suitable for the analysis of A. digitata fruit components. High electro deposition rates and redox efficiencies revealed the significant role of the proton to the redox process. The broad objectives were to adopt derivatized electrodes (DE) in electrochemical characterization of Adansonia digitata fruit
