“…Different efforts to promote loss of green color in yerba-mate ageing were performed in recent years. Process to produce this feature involved the use of controlled conditions of humidity and temperature (Zaions et al, 2014), such as UV light (Lewinski et al, 2015). In laboratory scale, UV light produced important changes in green color in 72 hour, adjusting the changes to exponential model (Lewinski et al, 2015).…”

Purpose – The purpose of this paper was to assess the changes in secondary metabolites and color during yerba-mate aging under controlled conditions. In Uruguay and Paraguay, the yerba-mate matured, in which chlorophyll degradation occurs, is preferred. For the matured product, the yerba-mate is stored for six months to one year. Design/methodology/approach – Processed yerba-mate was submitted to 35°C and 80 per cent humidity during 42 days in a climatic chamber. Samples were collected every seven days, and the phenolic compounds/methylxanthines were quantified by ultra-performance liquid chromatography – photodiode array and chlorophylls/phaeophytins by spectrophotometry. L*, a* and b* colorimetric coordinates were measured. Findings – The most expressive changes in the color occur in the first 14 days. At this time, 23.161 ± 2.984 per cent of total chlorophyll was degraded, considering that in 42 days, 37.458 ± 0.955 per cent is degraded, according to an exponential model. A positive correlation between theobromine amount and maturation time was found. This was verified by an increase in dicaffeoylquinic acid concentrations and small changes in chlorogenic acid isomers. Practical implications – The results indicate that this is a viable accelerated yerba-mate maturation process according to economics and nutraceutics. Originality/value – The paper has reported here a novel strategy to promote the yerba-mate maturation using controlled conditions.

“…One of the most popular species is Ilex paraguariensis A.St.-H, an evergreen tree or shrub that grows in temperate or tropical climates in southern Brazil, in the northeast of Argentina, and in Paraguay [ 6 , 9 ]. This plant has great functional importance in South America and is thus a comparative species due to its well-documented composition and biological properties [ 10 , 11 ] and it is used to make traditional infusions processed from leaves and twigs called “Yerba mate”, “erva mate” or “chimarrão” [ 12 , 13 ]. This herbal product has gained great cultural significance and is a daily beverage consumed by people in South America [ 14 ].…”

Plants of the genus Ilex are widespread throughout the world, with its best-known representative being Ilex paraguraiensis from South America. The European species Ilex aquifolium shows similarities in its terpenoid, sugar and phenolic acid profiles. Using aqueous extracts of Ilex aquifolium as a supplement in Wistar rats showed that, despite the lack of caffeine, it had strong hypocholesterolemic effects. In addition, a reduction in oxidative lipid degradation and a decrease in hepatic steatosis in histopathological studies were observed. The results of this study suggest that extracts from the European species Ilex aquifolium may have potential as an alternative treatment for hyperlipidemia.

“…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). The selection of plants that produce high concentrations of secondary metabolites can also be performed towards this aim.…”

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.
