In this study, a voltammetric method was developed for the electrochemical determination of rutin. The pencil graphite electrode was a disposable and low cost electrode. It showed a very good catalytic effect with the significant augmentation of the peak current of rutin oxidation compared to the glassy carbon electrode. Under the optimized conditions, the pencil graphite electrode had two linear responses from 0.104 to 166.70×10-7 M and from 166.70 to 1060.60×10-7 M rutin, the detection and quantification limits were calculated, which were 1.13×10-9 M (S/N=3) and 3.42×10-9 M, respectively. The percentage of recoveries were obtained in a range between 98.98 and 101.02 % for five successive determinations of rutin, which show agreeable repeatability. The developed method was successfully employed for the direct determination of rutin in real samples such as buckwheat, green tea and red apple. Finally, the interference effects of some species to the determination of rutin were also evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
