%X In this study, an electrochemical method was developed for the determination of rutin. The pencil graphite electrode, a disposable and low cost electrode, showed a very good catalytic effect with the significant enhancement of the peak current compared to the glassy carbon electrode. Under optimized conditions, the pencil graphite electrode had two linear ranges from 0.39 to 166.70กม10-7 M and 166.70 to 1060.60กม10-7 M rutin, the limit of detection was also obtained 1.13 nM (S/N=3). The percentage of recoveries were obtained in a range between 98.98 and 101.02 % for five successive determinations of rutin, which indicate acceptable repeatability. This method was successfully applied 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 was also evaluated
