Abstract: | The present work describes the first electrochemical investigation and a simple, rapid and modification‐free electroanalytical methodology for quantification of hordenine (a potent phenylethylamine alkaloid) using a boron‐doped diamond electrode. At optimized square‐wave voltammetric parameters, the observed oxidation peak current in 0.1 M HClO4 at +1.33 V (vs. Ag/AgCl) increased linearly from 5.0 to 100 μg mL?1 (3.0×10?5–6.1×10?4 M), with detection limit of 1.3 μg mL?1 (7.8×10?6 M). The applicability of the developed method was tested with the determination of hordenine in the commercial dietary supplement formulations. |
