Abstrakt:
This work has been focused on clarification of the electrochemical behaviour of β-carotene (BCA) in different non-aqueous media at conventional solid working electrodes; namely, glassy carbon, platinum, and gold electrode. A probable reaction pathway of the electrochemical oxidation BCA is proposed. BCA undergoes irreversible electrochemical oxidation in several steps corresponding to anodic hydroxylation and oxidation reactions of double bonds. According to the calculation of molecular electron density, it can be assumed that a double bond on the fifteenth carbon (C15) is involved in the mentioned processes, having provided the first anodic peak applicable to analytical purposes.
