Özet

Sesamol is a phenolic compound naturally found in sesame seeds. It has beneficial health effects in humans, as it features significant antioxidant activity and has anticancer and anti-aging properties. Therefore, finding a suitable electrode surface for sesamol determination is important. The prominent advantage of boron-doped diamond electrodes is their use in many sensing platforms without the need for the surface modification. This study represents the first time that sesamol has been determined using boron-doped diamond electrodes in acidic media by square wave voltammetry. Linear responses of sesamol were obtained in the concentration range from 0.2 µM to 1000 µM, and the detection limit was determined to be 85 nM based on a signal-to-noise ratio of 3. The relative standard deviations were 2.1% for a 1 µM standard with three measurements.
