“…Reverse-phase high-performance liquid chromatography (RP-HPLC) methods with electrochemical (EC) glassy carbon detectors have been widely used for the separation, detection and identification of polyphenols in different extracts and plant materials [30,32,33]. The electrochemical detectors enable highly selective and sensitive results, and it is possible to modify the experimental conditions, such as the electrolyte ionic strength, buffer and pH, in order to maximize the sensitivity.…”

Flavonoids in Calligonum polygonoides Linnaeus extract were separated, detected, and identified by reverse‐phase high‐performance liquid chromatography (RP‐HPLC) with electrochemical detection (EC) in combined isocratic and gradient elution using a glassy carbon or a boron doped diamond electrode. Ultrasonication coupled with a microwave‐assisted technique was developed to optimize the extraction of the phenolic compounds. The total antioxidant capacity was quantified using the DPPH. method and voltammetry. The RP‐HPLC‐EC led to the detection of nine different flavonoids: catechin, delphinidin, fisetin, myricetin, epicatechin, kuromanin, rutin, callistephin and procyanidin A2, in a single run by direct injection of the sample extract solution.

“…Several hundreds of reviews [26], [27] and [28] were published on applications of these electrodes in cyclic voltammetry for the analysis of pesticides, herbicides, pharmaceutical products [29], [30] and [31]. The conductive diamond was also used to manufacture electrodes for electrochemical detection in HPLC and flow injection [32], [33], [34], [35], [36], [37] and [38] electrochemical reactions [39].…”

“…Different strategies have been applied for determination of these undesirable constituents, such as gas chromatography (GC) with electron capture detection for the determination of pyrethroids, 56 HPLC with fluorescence detection for the simultaneous determination of abamectin and ivermectin, 57 and HPLC with amperometric detection using a boron-doped diamond electrode for the simultaneous determination of sulfomethoxazole and trimethoprim. 58 All these procedures are important for applying regulative legislation and public health. Another significant application is the control of the composition of juices.…”

A química brasileira está crescendo rapidamente, sendo um dos principais alicerces para o contínuo desenvolvimento do país. Inspirados no 15º Encontro Nacional de Química Analítica, ENQA, com um número recorde de participantes e comunicações, decidiu-se revisar os recentes desenvolvimentos em química analítica no Brasil. Foram escolhidas as mesmas áreas de aplicação adotadas para a organização temática do ENQA e selecionados artigos publicados por autores brasileiros em 7 periódicos de ampla penetração na área. Os dois periódicos científicos editados pela Sociedade Brasileira de Química também foram pesquisados. Esta revisão não é exaustiva, porém os trabalhos selecionados após 2008 mostram uma significativa visão geral da área. Pode-se concluir que a química analítica brasileira está saudável, em crescimento e certamente atenderá as demandas do país como uma potência emergida.Chemical sciences in Brazil are growing fast and being one of the main supports for the continuous development of the country. Inspired on the 15 th Brazilian Meeting on Analytical Chemistry, ENQA, with a record number of participants and communications, we have decided to review recent developments in analytical chemistry in Brazil. We have chosen the same application areas used for the thematic organization of the ENQA and have searched papers published by Brazilian authors in 7 major and general journals in analytical chemistry. The two scientific journals published by the Brazilian Chemical Society were also searched. This review is not comprehensive, but the selected papers published after 2008 shown an impressive overview of the area. We may conclude that analytical chemistry is healthy and growing in Brazilian scenario and certainly will attend the demands of Brazil as an emerged power.
