“…Other works assessing genetic variability of mate provenances by RAPD markers also showed greater diversity within populations with values of 85%, 80%, and 88.3%, respectively. [20][24] [30] This result is expected as mate has characteristics that contribute to greater intra-population variability. Mate is a cryptic dioecious species, with mandatory cross-fertilization, pollination carried out by insects and wide natural distribution.…”

The aim of this study was to evaluate the phytochemical and genetic diversity, relationships and identification of mate (Ilex paraguariensis A.St.-Hil.) elite genetic resources belonging to the Brazilian germplasm collection and mate breeding program. Mate has been studied due to the presence of phytochemical compounds, especially methylxanthines and phenolic compounds. The samples were collected from the leaves of 76 mate elite genetic resources (16 progenies × 5 localities). Total DNA was extracted from mate leaves and 20 random primers were used for DNA amplification. Methylxanthines (caffeine and theobromine) and phenolic compounds (chlorogenic, neochlorogenic, and criptochlorogenic acids) were quantified by HPLC. The genetic divergence estimated was higher within (92%) than among (8%) the different populations. Analysis of genetic distance between origins provided the formation of two groups by UPGMA cluster analysis, with higher polymorphism (94.9%). The average content of caffeine ranged from 0.01 to 1.38% and theobromine of 0.10 - 0.85% (w/w). The caffeoylquinic acids concentrations (1.43 - 5.38%) showed a gradient 3-CQA > 5-CQA > 4-CQA. The coefficient of genetic variation (CVg) was of low magnitude for all mono-caffeoylquinics acids. Significant correlations (positive and negative) were observed between the phytochemical compounds. Genetic diversity analysis performed by RAPD markers showed a greater intra-populational diversity; genetic resources with low caffeine and higher theobromine content were identified and can be used in breeding programs; the correlation between methylxanthines and phenolic compounds can be used as a good predictor in future studies.

“…Análises e estudos sobre a erva-mate revelam diversas propriedades nutritivas e farmacêuticas tais como: antioxidante, antimicrobiana, diurética, digestiva, cicatricial e estimulante, conferindo um grande potencial de aproveitamento (Asolini et al, 2006;Filip et al, 2000;Gorzalczany et al, 2001;Gonçalves et al, 2005;Kowalczyk et al, 2006;Vidor et al, 2002).…”

"Antimicrobial activity of extracts of the leaves and branches of Ilex paraguariensis (erva-mate)". For the evaluation of the antimicrobial activity of Ilex paraguariensis six microorganisms were used: Candida albicans, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus and Staphylococcus epidermidis. In disks of filter paper 10 µl of hydro-alcoholic extracts of the leaves and branches from two distinct environments were added, with and without sun exposure. The extracts have inhibited levedura, gram-negative bacillus and gram-positive cocos, with no activity to Escherichia coli.

“…Essa espécie é consumida habitualmente na Argentina, no Paraguai, no Uruguai e no Brasil, onde apresenta grande importância econômica, social e ecológica. Dentre as inúmeras aplicações, predomina a produção de bebidas, como o chimarrão, o tererê e o chá-mate (COELHO et al, 2002;VIDOR et al, 2002). Essa planta chamou a atenção da comunidade científica nos últimos anos por seus efeitos benéficos à saúde humana, principalmente com relação à atividade antioxidante e protetora frente a processos degenerativos como os que levam ao desenvolvimento de doenças cardiovasculares e a danos ao DNA (MACHADO et al, 2007).…”

Devido à carência de informações a respeito da propagação vegetativa de erva-mate, conduziu-se um experimento com o objetivo de avaliar o ambiente de enraizamento e composições de substrato na sobrevivência, enraizamento e vigor de estacas de Ilex paraguariensis de plantas de 12 anos de idade. Testou-se o efeito de três clones (A32, A34 e A36), seis substratos (S1 - substrato para enraizamento à base de casca de pinus; S2 - substrato para enraizamento à base de casca de pinus e vermiculita; S3 - casca de arroz carbonizada + vermiculita fina + substrato para enraizamento à base de casca de pinus e vermiculita (1:1:1 v/v); S4 - casca de arroz carbonizada + substrato para enraizamento à base de casca de pinus e vermiculita (1:1 v/v); S5 - casca de arroz carbonizada + vermiculita fina (1:1 v/v); S6 - fibra de coco) e dois ambientes de enraizamento (casa de vegetação automatizada e simples). Embora não tenham ocorrido grandes variações entre os ambientes testados, o enraizamento das estacas mostrou-se baixo. O uso da mistura de casca de arroz carbonizada + substrato para enraizamento à base de casca de pinus e vermiculita na proporção 1:1 (v/v) é aconselhado para estaquia de erva-mate.
