摘要

马鞭草糖苷是从马鞭草科的整个植物中分离出来的,具有显著的生物活性。在这项工作中,我们报道了从越南收集的Clerodendrum inme茎中分离出的一种酚类苷类化合物verbascoside,并通过与文献报道的光谱数据进行比较来验证其结构。然后将毛蕊花糖苷作为单体应用于电化学沉积一层聚毛蕊花糖苷到玻碳电极上,以实现Cu2+感应。电化学结果表明,与Ni2+和Co2+等其他评价离子相比,聚戊二苷修饰的玻碳电极对Cu2+离子具有较高的选择性。该传感器检测Cu2+的浓度范围为0 ~ 175 μM,灵敏度为0.372µaµM−1,检测限为50 nM。

Verbascoside extracted from Clerodendrum inerme: A natural monomer for the fabrication of a sensitive electrochemical Cu(II) sensor
Verbascoside is isolated from the whole plants of the Verbenaceae family and demonstrates significant levels of bioactivity. In this work, we report on the isolation of verbascoside, a phenolic glycoside, from the stems of Clerodendrum inerme collected in Vietnam and verify its structure by comparing its spectroscopic data with those reported in the literature. Verbascoside is then applied as a monomer for the electrochemical deposition of a layer of polyverbascoside onto glassy carbon electrodes toward Cu2+ sensing. Electrochemical results demonstrate that the polyverbascoside-modified glassy carbon electrode is highly selective for Cu2+ ions compared to other evaluated ions including Ni2+ and Co2+. The developed sensor can detect Cu2+ in a concentration range from 0 to 175 μM with a sensitivity of 0.372 µA µM−1 and a limit of detection of 50 nM Cu2+ ions.

期刊介绍: The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
