“…Several authors evaluated the antioxidant activity of I. paraguariensis extracts (de Mejía et al, 2010;Peres et al, 2013;Blum-Silva et al, 2015), though they have used different methods or expressed their results in distinct units, making it impossible to compare them with our results. Berté et al (2011) reported a much lower DPPH scavenging activity for an aqueous spray-dried extract of yerba mate from Brazil (EC 50 value 2520 µg/mL) than the one determined herein.…”

Leaves, stems and whole plant of Ilex paraguariensis (yerba mate) were characterized in terms of their chemical composition and biological activities in order to determine which part of the plant is more interesting to develop bioactive formulations. The yerba mate samples contain at least five free sugars, five organic acids, eighteen fatty acids, one tocopherol, nine hydroxycinnamoyl derivatives and two flavonols. The leaves extract revealed the highest antioxidant activity, correlating with its highest levels of phenolic compounds. By contrast, the stems extract showed the highest antiinflammatory potential and was also the most potent against MCF-7 and HepG2 cell lines, probably due to the presence of other phytochemicals. The absence of hepatotoxicity of the extracts was confirmed in porcine liver primary cells. Although the yerba mate extracts have been widely studied, this report shows for the first time the distinct potentialities of each individual part of the plant.

“…These programs aim at selecting genotypes with additional adaptive traits to environmental cultivation conditions, high-leaf mass production, and tolerance to biotic and abiotic factors. Recently, emphasis has been placed on the inclusion traits linked to the content of some relevant chemical compounds that can directly affect the quality of commercial products and on their biological effects (Morais et al, 2009;González de Mejía et al, 2010;Sturion & Resende, 2010;Anesini et al, 2012;Barbosa et al, 2015;Blum-Silva et al, 2015;González Arbeláez et al, 2016;Cardozo Junior & Morand, 2016). However, increasing productivity is always desirable for breeding programs.…”

The objective of this work was to evaluate the feasibility of early selection of open-pollinated yerba mate (Ilex paraguariensis) progenies, and to classify the best parents and candidates for clones. The germplasm is composed of 140 progenies collected from areas within the natural distribution of the species in Southern Brazil and a commercial genotype (control). The experiment was established in Ivaí, in the state of Paraná, Brazil, in March 1997, in randomized complete blocks, with ten replicates, and linear plots of six plants. The commercial mass (kg per plant) of leaves and branches smaller than 7 mm was harvested at 2.5, 4.5, 6.5, and 18.7 years of age. The statistical evaluation was performed using the mixed model procedure with restricted maximum likelihood/best linear unbiased prediction, using the Selegen software. High selective accuracy, significant progeny effects, and genetic variability for commercial mass production were observed for the four harvesting ages. The application of early selection for leaf mass production is feasible for yerba mate progenies harvested at 6.5 years. The selection of the best trees, either for use as parents or as candidates for cloning, provides significant gains for the genetic breeding of yerba mate.

“…According to Dartora et al [27], yerba-mate directly exposed to sunlight has higher levels of phenolic compounds as compared with the shaded plant. Blum-Silva et al [28] reported that the concentration of phenolic compounds is higher in younger leaves. However, Strassmann et al [29] found greater concentration of total phenolic compounds in aqueous extracts of cultivated yerba-mate leaves, either young or adult (149.68 and 135.40 µg/mL, respectively) in comparison to native leaves (64.08 µg/mL and 59.30 µg/mL, respectively).…”

Novel Beverages of Yerba-Mate and Soy: Bioactive Compounds and Functional Properties

et al. 2018

In this paper, two high-nutrition commodities that are produced in great amounts in Brazil were joined in a single functional product. Yerba mate (Ilex paraguariensis) is rich in bioactive compounds, while soybean is a high-quality protein source. The objective of this paper was to assess the psychochemical characteristics of two yerba-mate progenies (planted-PL and native-NT leaves) and then confirm whether the functional and nutritional properties of the main ingredients were conveyed to the beverage produced. The main raw material, yerba-mate leaves, and the drinks were assessed for bioactive compounds, antioxidant capacity, physicochemical properties, and nutritional value. Planted leaves showed higher concentration of 5-CQA, caffeic acid and rutin than the native plant, whereas caffeine and theobromine were detected in larger amounts in native leaves. The nutritional profile of the drinks was compared to commercial beverages-either yerba-mate-based or soy-based. They indeed provide more protein, fiber, and fats than traditional yerba-mate beverages (chimarrão, tererê, and mate tea). Soy drinks currently marketed, for their turn, have similar caloric value and higher contents of lipid and protein as compared to our product, but are poor in fibers. NT drink (DPPH-IC 50 92.83 and ABTS-8.18 µM Trolox/mL) had higher antioxidant activity than PL (IC 50 147.06 and 5.63 µM Trolox/mL) due to the greater volume fraction of yerba-mate extract. NT beverage has more 5-CQA and caffeine in the same intake of tererê and traditional mate tea. This healthy beverage contributes to an increasing income to the food industry and yerba-mate producers, and environmental gains that are related to the exploration of natural resources.
