Summary
This study presents a new electroanalytical method using square wave voltammetry to detect sesamol (Ses) in sesame oil. The developed assay is accurate and reliable for quantifying sesamol in commercial samples.
Area of Science:
- Analytical Chemistry
- Electrochemistry
Background:
- Sesamol is a key compound in sesame oil with potential health benefits.
- Accurate quantification of sesamol is important for quality control and research.
Purpose of the Study:
- To develop and validate an electroanalytical assay for sesamol determination.
- To investigate the electrochemical behavior of sesamol.
Main Methods:
- Square wave voltammetry (SWV) was employed for quantitative analysis.
- Cyclic voltammetry (CV) was used to study electrochemical properties.
- Optimization of supporting electrolyte and SW parameters was performed.
Main Results:
- A linear relationship was observed between peak current and sesamol concentration (3.0–140.0 μmol L⁻¹).
- The method achieved a low limit of detection (0.71 μmol L⁻¹).
- The electrode process was confirmed to be diffusion-controlled.
Conclusions:
- The developed SWV method is a sensitive and effective tool for sesamol quantification in sesame oil.
- Results showed good agreement with the HPLC-UV reference method, indicating reliability.
