Flavonoids, a benzo-γ-pyrone derivatives, have received significant interest because they help treatment of health problems
on human. Especially, rutin is important flavonoid present in plants, drinks and medicinal herbs . Rutin (Ru) is known
with its anti-bacterial, anti-inflammatory, anti-oxidation and anti-aging abilities . So, it is necassary to develop a sensitive
method to determine Ru in food and medicine.
This study aims to fabricate a pencil graphite electrode (PGE) coated with 2-mercaptobenzothiazole using cyclic
voltammetry (CV). This electrode was characterized by electrochemical impedance spectroscopy and used for
determination of Ru by differential pulse voltammetry (DPV). Therefore, the effects of covering cycle, supporting
electrolyte and pH were investigated to find optimum conditions. The modification procedure of PGE was performed
between -1 and +2.0 V potential range with 15 CV at 100 mV s-1
scan rate. The fabricated electrode was successfully used
to determine Ru in real samples.
