Background: Yerba mate, a popular, tea-like beverage prepared from the dried leaves of Ilex paraguariensis, is widely consumed, and has several reported health benefits. Compared with other herbal teas, the effect of yerba mate on human cells in the context of cancer has not been extensively studied. The method of extraction of bioactive compounds from the yerba mate leaves plays an important role in its effect on cancer cells. Methods: In this study we assessed the viability, anti-proliferative, and apoptotic effect of the aqueous yerba mate extract, prepared using the same conditions employed for consumption, on different human colorectal cancer cell lines (Caco-2, HT-29, and HCT116) and on the non-tumorigenic human colon epithelial cell line (NCM460).Results: Cytotoxicity of aqueous yerba mate extract was studied and a dose-dependent decrease in viability was observed in all the tested cell lines. At 24 hrs., viability decreased to 19.7% with Caco-2 cells, 2.7% with HCT116, and 8.4% with HT-29 cells at a concentration of 4.8 mg/mL of yerba mate extract. The effect was less prominent on the NCM460 cell line where the viability of cells at the same concentration was 65.2%. Yerba mate extract also showed concentration-dependent anti-proliferative effects as determined by the WST-1 proliferation kit. IC50 values ranged between 0.22-0.69 mg/mL at 24 hr for cell lines tested. To study whether cell death was due to apoptosis, Caco-2 cells were stained with Annexin V-FITC assay and an increase in the percentage of late apoptotic Caco-2 cells was observed with yerba mate extract at 0.6-4.8 mg/mL. Cell cycle analysis using DNA content by flow cytometry showed an increase in the percentage of Caco-2 cells in the subG0/G1 phase and the G0/G1 phase after treatment with 2.4 mg/mL extract. Collectively, our data suggest that yerba mate aqueous extract exhibits an anti-proliferative effect on tested cell lines by inducing apoptosis.  Conclusions: Yerba mate aqueous extract exhibits a strong anti-proliferative activity against adenocarcinoma cell lines studied and constitutes a promising functional food adjuvant to anti-cancer therapy. Further work is needed to identify active components and mechanisms of action. Keywords: Aqueous extract, yerba mate, anti-proliferative activity, adenocarcinoma cell lines

Stems And Leaves

Introduction: The stems and leaves of Ilex paraguariensis are popularly used for tea infusions in South America and the Middle East. The health benefits have been previously studied, revealing anti-mutagenic, anti-oxidant, hepatoprotective, hypocholesteremic and glycemic improvement. Limited research was performed on the antibacterial activity of the aqueous extract of Yerba Mate on standard and clinical isolates of Gram-positive and Gram-negative bacteria. Methodology: Commercial Ilex paraguariensis stems and leaves were ground and extracted with sterile deionized water at 70°C. Four ATCC bacterial strains and twenty-five bacterial clinical strains were used for testing. To obtain the minimal inhibitory concentration (MIC), the Yerba Mate aqueous solution was serially diluted according to the microdilution method. For the minimal bactericidal concentration (MBC), the tubes with clear broth were sub-cultured. To identify the types of ESBLs present in the clinical isolates, a multiplex PCR was performed. Results: An antibacterial activity was observed against most of tested strains, with a greater activity against Gram-positive bacteria. MIC and MBC values ranged between 0.468 mg/mL and 15 mg/mL of aqueous extract of Yerba Mate. Conclusion: The aqueous extract of the stems and leaves of Ilex paraguariensis extracted at 70°C showed a significant antibacterial activity. There was no correlation found between the different molecular resistance profiles and the antibacterial activity range.

Introduction: Limited research was performed on the antibacterial activity of the aqueous extract of Yerba Mate. The purpose of this study is to evaluate the anti-bacterial activity of Yerba Mate against Gram-positive and Gram-negative bacterial strains and its action against some resistant bacteria with genotypic molecular testing of resistance profiles. Methodology: Commercial Ilex paraguariensis stems and leaves were purchased and extracts were prepared by adding water at 70oC for 2 hrs. ATCC bacterial strains and clinical strains from Centre Hospitalier Du Nord (CHN) were used for testing. Macro dilution method was used to determine the minimal inhibitory. Minimal bactericidal concentration (MBC) was determined by sub-culturing the tubes with clear broth. For phenotypic and genotypic detection of β-lactamases, Double Disk Synergy method, E-test, phenylboronic acid disc method and multiplex PCR were performed for the identification of the mechanisms of resistance. Results: Antibacterial activity was observed against all tested strains, with a greater activity against Gram-positive bacteria. This study showed mostly a greater antibacterial activity of aqueous extract of Yerba Mate in comparison to different extraction methods published. In general, the MIC and MBC values ranged between 0.468 mg/mL and 15 mg/mL. No correlation was found between the different molecular resistance profiles and the antibacterial activity. Conclusion: More studies are needed to determine the molecule or molecules responsible for this activity. Moreover, testing a wider range of bacterial isolates is important for a better understanding of the potential role of Yerba Mate.

Abstract Ilex paraguariensis, commonly known as yerba mate, is a tree species native to South America. Its commercial value is due to the manufacturing of teas, with potential also in the pharmacological and cosmetic industries. Vegetative propagation of yerba mate is considered an innovation to the traditional production systems based on sexual propagation. The present study aimed to evaluate the rhizogenic potential and chemical attributes of mini-cuttings from 15 yerba mate genotypes, as well as to verify the correlation between phytochemical and rooting-related variables. Mini-cuttings were collected from a pre-existing mini-clonal hedge and the experimental design was completely randomized, with 15 treatments (genotypes), four replications and 10 mini-cuttings per plot. After 120 days, mini-cuttings were assessed regarding rooting, mortality, callogenesis and leaf retention percentages, percentage of mini-cuttings with both calluses and roots, number of roots and average root length. At the time of collection, subsamples from each plot were used for phytochemical analyses including total phenolic compounds, protein, caffeine and theobromine contents and antioxidant activity. Rooting percentages ranged from 5 to 72.5%, with significant variation among genotypes. Adventitious rooting and phytochemical profile of yerba mate mini-cuttings are genotype-dependent. Leaf retention is a relevant factor in the rooting of yerba mate mini-cuttings and the levels of total phenolic compounds, antioxidants and theobromine present in mini-cuttings are negatively correlated components to Ilex paraguariensis adventitious rooting.

O controle da broca-da-erva-mate, Hedypathes betulinus, limita-se ao emprego de práticas silviculturais e catação manual dos insetos adultos, não sendo permitido o uso de inseticidas químicos na cultura. Esta pesquisa teve por objetivos verificar a presença natural de Beauveria bassiana no solo de plantio em monocultura de erva-mate, determinar a persistência de B. bassiana no solo após duas e três aplicações do fungo e averiguar a influência de fatores abióticos na estabilidade do fungo no solo. O estudo foi conduzido em um erval no município de Campo Alegre, Santa Catarina, Brasil, onde foram coletadas amostras de solo em duas áreas, para avaliação da presença natural de inóculos do fungo B. bassiana, procedendo-se à contagem, isolamento e identificação.Não foi detectada a ocorrência natural do fungo no solo em nenhuma das duas áreas. Após essa confirmação, foram realizadas pulverizações com B. bassiana em ambas as áreas, sendo que em uma ocorreram duas e na outra três aplicações. Após a última pulverização, realizada em fevereiro/2006, verificou-se que os inóculos do fungo persistiram por 90 dias na área com duas aplicações e 120 dias na área com três aplicações. A temperatura afetou a persistência do fungo no solo em ambas as áreas, mas a umidade relativa não mostrou influência sobre os inóculos em campo.Palavras-chave: Broca-da-erva-mate; controle biológico; epizootia; fungo entomopatogênico. AbstractPersistence in soil of inoculum of Beauveria bassiana used to control Hedypathes betulinus in yerba maté plantation, Ilex paraguariensis. Control measures of Hedypathes betulinus are restricted to agricultural practices and hand picking of adult insects. No chemical control is allowed in yerba maté cultivation areas. The objectives of this research were to verify the natural occurrence of the entomopathogenic fungus Beauveria bassiana in the soil of yerba maté in monoculture; to determine the persistence of inoculums in the soil after applications of the fungus; and to evaluate the influence of abiotic factors on fungus stability in the soil. The soil samples were taken from two experimental areas in a yerba maté plantation in the county of Campo Alegre, Santa Catarina, Brazil. The samples were analyzed in order to count, isolate and identify inoculums of B. bassiana and other fungi. After the confirmation that B. bassiana was not present in the soil, a suspension of the fungus was applied, twice in one of the areas and three times in the other. After the last application in February/2006, the inoculum persisted for 90 and 120 days, in the area with two and three applications, respectively. The temperature affected the persistence of B. bassiana in soil; however, the relative humidity did not.Keywords: Biological control; epizooty; entomopathogenic fungus; wood borer.
