“…A different phytochemical profile among plants was described in coffee (Garrett et al, 2013) and Camellia sinensis (Thomas et al, 2006) cultures. Some plant secondary metabolites can prevent the cellular damage produced by oxidative stress, including phenolic acids and flavonoids (Bubols et al, 2013;Evans, 2002).…”

Yerba-mate (Ilex paraguariensis St. Hil) is a native South American species. Plant progenies are populations that differ in terms of their productivity, morphology and phytochemical profile. This study aimed to determine the concentration of primary and secondary metabolites, such as antioxidants, in leaves, of yerba-mate progenies selected based on morphological characteristics. We evaluated the centesimal composition of secondary metabolites in the leaves of five yerba-mate plants. Methylxanthines and phenolic compounds were determined by UPLC-PDA, and antioxidant activity by measuring DPPH scavenging. Significant differences were found in centesimal composition and the contents of caffeine, theobromine, rutin and chlorogenic acid, as well as antioxidant activities, in selected progenies. The IC 50 values were correlated with the chlorogenic acid levels (r 2 = 0.5242) and soluble content (r 2 = 0.7686). The morphological characteristics observed in yerba-mate leaves can be used as a tool for plant selection, to obtain matrices with different phytochemical profiles as a genetic material source.Index terms: Ilex paraguariensis St. Hil.; plant selection; secondary metabolites. RESUMOA erva-mate (Ilex paraguariensis St. Hil) é uma espécie nativa da América do Sul. Progênies vegetais são grupos de plantas que apresentam diferenças em relação a sua produtividade, morfologia e possivelmente perfil fitoquímico. Neste trabalho, objetivou-se determinar os teores de metabólitos primários e secundários, assim como atividade antioxidante em folhas de progênies de erva-mate, morfologicamente caracterizadas. Foi avaliada a composição centesimal e níveis de metabólitos secundários em cinco plantas. Metilxantinas e compostos fenólicos foram determinados por UPLC-PDA, e a atividade antioxidante, por meio da medição da capacidade de sequestro do radical DPPH. Foram encontradas diferenças significativas na composição centesimal, e no conteúdo de cafeína, teobromina, rutina e ácido clorogênico, assim como atividade antioxidante nas progênies selecionas. Os valores de IC 50 estiveram correlacionados com os níveis de ácido clorogênico (r 2 = 0,5242) e conteúdo de solúveis (r 2 = 0,7686). Os caracteres morfológicos observados nas folhas de erva-mate podem ser utilizados como uma ferramenta visando a obter matrizes com perfil fitoquímico diferenciado como fonte de material genético.Termos para indexação: Ilex paraguariensis St. Hil.; seleção de plantas; metabólitos secundários.

“…These peptides, known as Ricinus communis biomarkers or RCBs, may be exploited as marker compounds for potential ricin exposure. The LC-MS-based chemical analysis has previously been applied to the determination of cultivars of Salvia miltiorrhiza (Dai et al, 2010), arabica coffee (Garrett et al, 2013), green tea (Fujimura et al, 2011) and tomatoes (Siano et al, 2011).…”

“…In addition to bioanalysis, the commercial chip‐based LC‐MS systems have also been utilized to determine pesticides , coffee metabolites , mycotoxins , and bioactive compounds in different applications. For example, the NanoMate nanospray interface has been used to analyze pesticides and coffee metabolites . Eikel et al analyzed pesticides on various food surfaces using a TriVersa NanoMate nanospray interface with automatic LESA for MS analysis.…”

“…The sensitive LESA‐MS method (20‐fold lower than the EPA tolerance levels) offered a viable alternative screening method for food safety. Garrett et al examined coffee quality by analyzing the chemical compositions of various arabica coffee cultivars using ESI Fourier transform ion cyclotron resonance (FT‐ICR) MS with direct infusion. Green coffee samples were ground, sieved, and extracted with methanol.…”

Many microfluidic chip-based LC-MS systems have been utilized for high-throughput analysis in various fields of bioanalytical applications such as proteomic, glycomic, pharmaceutical, and clinical research. This review is an update of a previous review article (Electrophoresis 2012, 33, 635-643) to mainly cover the most recent advancements in chip-based LC-MS for determining small molecules in bioanalysis. First, the different types of microfluidic chip devices for chip-based LC-MS analysis will be discussed. Following the discussion of the recent developments in the chip-based instrumentation, the applications of chip-based LC-MS for determining small molecules, such as glycans, pharmaceutical drugs, drugs of abuse, drug metabolites, and biomarkers in various biological sample matrixes will also be included in this review.
