Voltammetry of vinblastine sulfate was carried out in acetonitrile containing 0.2 M of sodium perchlorate. The studies were done when 21.4 mM pyridine was present in the above background solution. Vinblastine sulfate gave a single anodic peak representing irreversible electrochemical oxidation, as shown in both cases. Although, the behavior of vinblastine sulfate was almost comparable in the presence/absence of pyridine. However, the studies carried in the absence of pyridine were more significant.
