Chlorogenic acid (5-O-caffeoylquinic acid) is a phenolic compound from the hydroxycinnamic acid family. Epidemiological, biological, and biochemical studies concur to support the beneficial role of chlorogenic acid in human health, along with other dietary phenolic compounds. Thus, chlorogenic acid has been reported to exert inhibitory effects on carcinogenesis in the large intestine, liver, and tongue, and a protective action on oxidative stress in vivo, together with anti-inflammatory, antidiabetic and antihypertensive activities. It is also claimed to have antifungal, antibacterial and antiviral effects with relatively low toxicity and side effects, alongside properties that do not lead to antimicrobial resistance. Due to its importance, numerous methods for determining chlorogenic acid (CGA), as well as for its derivatives from coffee beans and other plants, were elaborated. The most frequently used methods are infrared spectroscopy, high performance liquid chromatography (HPLC), capillary electrophoresis, liquid chromatography-mass spectrometry and chemiluminescence. Although these methods proved to be efficient for quantifying CGA and its derived products, a number of deficiencies were identified: they are time consuming, laborious, and require expensive instruments. Therefore, electrochemical methods have been developed and used in the determination of CGA in different nutraceuticals or food products. The present review aims to present the main progresses and performance characteristics of electrochemical sensors and biosensors used to detect CGA, as it is reported in a high number of relevant scientific papers published mainly in the last decade.
绿原酸(5-O-咖啡酰奎尼酸)是一种来源于羟基肉桂酸家族的酚类化合物。流行病学、生物学和生物化学研究都一致表明,绿原酸与其他膳食酚类化合物一样,对人体健康具有有益作用。因此,绿原酸已被报道对大肠、肝脏和舌的致癌作用具有抑制作用,并具有体内抗氧化应激的保护作用,以及抗炎、抗糖尿病和降血压活性。它还具有抗真菌、抗菌和抗病毒作用,毒性和副作用相对较低,同时具有不会导致抗微生物耐药性的特性。由于其重要性,已经制定了许多用于测定绿原酸(CGA)及其咖啡豆和其他植物来源的衍生物的方法。最常用的方法是红外光谱法、高效液相色谱法(HPLC)、毛细管电泳、液相色谱-质谱法和化学发光法。尽管这些方法被证明可以有效地定量 CGA 及其衍生产品,但也发现了一些缺陷:它们耗时、费力,并且需要昂贵的仪器。因此,已经开发并在不同的营养保健品或食品产品中用于测定 CGA 的电化学方法。本综述旨在介绍用于检测 CGA 的电化学传感器和生物传感器的主要进展和性能特征,因为它在过去十年中发表的大量相关科学论文中有报道。
