“…17 In South America, Maté has been traditionally used as a natural substance that boosts the immune system, stabilizes the nervous system, stimulates the mind, controls appetite, treats obesity, reduces stress, and delays aging. It is sold in many countries, aside from South America and the United States, as tea products and food supplements, and no side effects have been reported after its ingestion.…”

Background: This study was performed to investigate the effects of Maté extract on body weight and fat content in obese women [25.0 kg/m 2 ≤ body mass index (BMI) < 30 kg/m 2 ] aged 20-65 years after 6 weeks of its administration. Methods: The randomized, double-blind, placebo-controlled study was conducted in 33 women. Participants took the supplement, either 2 Maté tablets or 2 placebo tablets, twice daily before meals for 6 weeks. Body weight, body mass index (BMI), waist circumference (WC), and various safety parameters were monitored. Body composition was measured by dual-energy X-ray absorptiometry at baseline and after 6 weeks. Results: Average body weight and BMI did not show any significant changes; however, trunk fat percentage significantly decreased in the Maté group compared to that in the placebo group (-1.24% vs -0.16%, P= 0.03). In the Maté group, the body fat percentages showed a tendency to decrease. All safety parameters were within normal ranges in both groups. Two participants, one from each group, reported nausea during the study. Conclusion: Maté extract significantly reduced trunk fat in obese women after 6 weeks, which indicates that it could improve abdominal fat mass. Furthermore, the supplement is safe and well tolerated.

“…A Ilex paraguariensis é uma planta da família Aquifoliaceae, conhecida popularmente como ervamate (13) , produzida e comercializada principalmente no Brasil, Uruguai, Paraguai e Argentina (14) . No Brasil, o cultivo e colheita da planta se dão pelo extrativismo da floresta natural ou pelo sistema misto, em que se combina o crescimento da floresta com melhores práticas de cultivo (15) .…”

ResumoA erva-mate vem sendo estudada devido às diversas atividades biológicas já evidenciadas. Este estudo teve como objetivo avaliar o efeito antimicrobiano, pelo método de difusão em disco, da adição de extratos de erva-mate frente à Escherichia coli e ao Proteus mirabilis previamente isolados da carne de peito de frango. Foram utilizadas diferentes concentrações de extrato (125 mg/mL, 250 mg/mL, 550 mg/mL de extrato de erva-mate, controle negativo com solução salina 0,85% e erva-mate pura) em triplicata e os resultados analisados pelo SAS ® 5.1. Quanto maior a concentração de extrato aplicada, maior (P<0,0001) foi o halo de inibição formado para as duas bactérias avaliadas, sendo que para a E. coli os halos foram menores quando comparados com os halos para o P. Mirabilis. Foi possível estimar a concentração de 400 mg/mL como sendo a mais eficiente frente ambas as bactérias avaliadas.

This study aimed to evaluate the antimicrobial effect of the addition of yerba mate extracts against Escherichia coli and Proteus mirabilis previously isolated from chicken breast meat using the disk diffusion method. Different extract concentrations were applied (125 mg/mL, 250 mg/mL, 550 mg/mL of yerba mate extract, negative control with saline 0.85% and pure yerba mate) in triplicate and the results were analyzed by the SAS ® 5.1. The increase in the concentration of the extract applied resulted in an increase (P<0.0001) in the inhibition zone formed for both bacteria, and it was evident that the inhibition zone for E. coli was smaller compared with the halos for P. mirabilis. It was possible to estimate the concentration of 400 mg/mL as the most efficient for both bacteria.

“…Literature studies indicate that the therapeutic efficacy focuses on diseases such as arthritis, inflammatory diseases, hemorrhoids, headache, hepatic disorders, and obesity [1,4,5]. A recent study conducted on rats indicates that I. paraguariensis plays an important role in the management of obesity by acting on the inflammatory profile [6].…”

“…The extracts contain mainly polyphenols like chlorogenic acid, purine alkaloids (methylxanthines) such as caffeine and theobromine, flavonoids, a combination of vitamins, tannins and numerous triterpenic saponins derived from ursolic acid [5,7,14]. The polyphenolic compounds of major importance in mate refer to caffeoyl derivatives, mainly monocaffeoyl quinic isomers and dicaffeoyl quinic isomers [7], and their level exceeds even that found in green tea, a typical 'antioxidant' product present on the market.…”

Qualitative and quantitative analysis of polyphenolic compounds in Ilex Sp. DOI: 10.1515/chem-2015-0142 received February 15, 2015 accepted October 1, 2015. Abstract: Natural compounds are an important source of desired biological activity which help to improve nutritional status, enhance productivity and bring many health benefits. The leaves of the Ilex paraguariensis (Aquifoliaceae) are used for preparing a beverage known as yerba mate and represent a proven source of natural polyphenols which are known to foster biological activity with the emphasis on antioxidant properties. In present work we focused on the polyphenolic content of air-dried leaves of Ilex aquifolium L., Ilex aquifolium 'Argentea Mariginata', Ilex meserveae 'Blue Angel', and a commercially available mate as the reference product. Liquid chromatography combined with mass spectrometry (HPLC and LC-MS) and thin layer chromatography (TLC), were used to establish polyphenolic substances content in aqueous methanolic extracts obtained from the biological matter. Up to 20 polyphenolic compounds were identified in the extracts, including rutin, quinic acid and its caffeoyl esters, i.e. chlorogenic acid and its isomers as well as dicaffeoyl derivatives. We took chlorogenic acid and rutin as reference compounds to quantify their levels in the extracts. It was determined that in all tested plants, high levels of these antioxidants were present. This led us to the conclusion that their leaves might serve as valuable food additives.
