“…The CF values were 130.52 ± 1.30%, 205.02 ± 1.10%, 332.49 ± 2.10% and 552.51 ± 3.34% for the first, second, third and fourth stages, respectively. The same behavior was observed by Aider et al (2007) for whey proteins and by Boaventura et al (2013) for aqueous extracts of mate, both submitted to FC. These authors obtained CF values of up to 500%.…”

“…Reports in the literature have shown that it is possible and advantageous to concentrate the phenolic compounds of vegetal extracts through freeze concentration (Boaventura et al, 2013;Belén et al, 2013) and nanofiltration (Conidi et al, 2011;Cassano et al, 2013), both processes being able to preserve the functionality.…”

“…Several strategies have been developed to obtain yerba-mate extracts with high levels of bioactive compounds, including freeze-concentration technology (Boaventura et al, 2012) and nanofiltration (Murakami et al, 2011;Prudêncio et al, 2012). The processing steps that affect the levels of phenolic compounds and methylxanthine have been assessed (Isolabella et al, 2010;Valerga;Lanari, 2012;Zaions et al, 2014).…”

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.

“…The Ilex paraguariensis has been extensively studied due to a variety of pharmacological antioxidant properties (Bravo et al 2007;Boaventura et al 2013a), bactericidal ability (Burris et al 2015), stimulant (Athayde et al 2000), diuretic, antidiabetic (Boaventura et al 2013b), usually attributed to the presence of phenolic compounds and alkaloids.…”

Traditionally, Ilex paraguariensis leaves are consumed in tea form or as typical drinks like mate and terere, while the fruits are discarded processing and has no commercial value. The aim of this work to evaluate phytochemical properties, total phenolic compounds, antioxidant and antimicrobial activity of extracts of Ilex paraguariensis fruits obtained from supercritical CO 2 and compressed propane extraction. The extraction with compressed propane yielded 2.72 wt%, whereas with supercritical CO 2 1.51 wt% was obtained. The compound extracted in larger amount by the two extraction solvents was caffeine, 163.28 and 54.17 mg/g by supercritical CO 2 and pressurized propane, respectively. The antioxidant activity was more pronounced for the supercritical CO 2 extract, with no difference found in terms of minimum inhibitory concentration for Staphylococcus aureus for the two extracts and better results observed for Escherichia coli when using supercritical CO 2 .
