Highly sensitive voltammetric method for hesperidin determination is developed using glassy carbon electrode modified with SnO2 nanoparticles (SnO2 NPs) and surfactants. The highest oxidation currents of hesperidin are observed in the case of cationic 0.50 mM cetylpyridinium bromide (CPB). Parameters of hesperidin electrooxidation have been calculated. Adsorptive anodic differential pulse voltammetry (AdADPV) in phosphate buffer pH 7.0 after 120 s accumulation provides linear dynamic ranges of 0.10–10 and 10–75 μM with the detection limit of 0.077 μM. The selectivity of hesperidin response is proved in the presence of inorganic ions, saccharides, ascorbic acid and other natural phenolics.

伏安法测定 SnO2 纳米颗粒和表面活性剂修饰电极上橙皮苷的含量

使用用 SnO 2纳米粒子 (SnO 2 NPs) 和表面活性剂修饰的玻碳电极开发了用于橙皮苷测定的高灵敏度伏安法。在阳离子 0.50 mM 溴化十六烷基吡啶 (CPB) 的情况下观察到橙皮苷的最高氧化电流。已经计算了橙皮苷电氧化的参数。磷酸盐缓冲液 pH 7.0 中的吸附阳极微分脉冲伏安法 (AdADPV) 在 120 秒积累后提供 0.10–10 和 10–75 μM 的线性动态范围,检测限为 0.077 μM。在无机离子、糖类、抗坏血酸和其他天然酚类物质的存在下证明了橙皮苷反应的选择性。
