Yerba mate tea is known as one of the most popular nonalcoholic beverages favoured by South Americans due to its nutrition facts and medicinal properties. The processing of yerba mate tea is found to affect the properties of its final forms. This study presents an investigation into the effects of water sources on the dissolution of yerba mate extract powders. Comparisons were conducted between yerba mate teas prepared by dissolving yerba mate extract powders into tap water and deionized water. Topics to be explored in this work are the major compositions and antioxidant activities, including total phenol content, reducing power, DPPH scavenging activity, and ABTS+• scavenging capacity. It is indicated that there is little difference for antioxidant activities and major constituents of yerba mate teas between both water sources. However, a deeper color is seen in the tap water case, resulting from the reaction between tannic acid and ions. This research finding can be treated as a way to benefit the yerba mate tea processing for applications.

Yerba-maté (Y-M), known as llex-paraquariensis is traditional South American herbal drink that is consumed as an aqueous extract from the Y-M leaves. This drink is thought to have long-term health benefits and thus it has recently gained more popularity. However, health hazards of polyaromatic hydrocarbons (PAHs) deposited in Y-M during drying process has been linked to the development of different types of cancer in particular oesophageal cancer. The current study developed and validated an extraction and analytical method to determine the presence of one of the PAH compounds, namely; benzo(b)fluoranthene [Bbf] as an indicator for the PAH(s) occurrence in Y-M in commercial samples of the dried leaves. Since the expected level of contamination with this compound is at trace level thus a sensitive and selective analytical method was needed. Gas Chromatography-Mass Spectrometry GC-MS method was developed using selected ion monitoring (SIM) with split-less mode focusing on 126 ion and 252 ion (main) for [Bbf]. The content of [Bbf] using different extraction methods was found in a range 0.02 to 0.09 μg/g. GC-MS results indicated a good repeatability of the peak area with strong correlation and linearity between mean peak area and concentration from the calibration curve. Soxhlet extraction using hexane as a solvent gave the highest yield of [Bbf] concentration. However, ultrasonic extraction using hot distilled water as a solvent is recommended as it better simulates the way of making and drinking.

Ilex paraguariensis(yerba mate) has a beneficial effect in the management of obesity. Here, we studied the effects of yerba mate on hypothalamic changes in leptin and insulin signalling, oxidative stress and liver morphology and metabolism in postnatal early overfeeding (EO) Wistar rats. To induce EO, the litter size was reduced to three pups per dam, and litters with 10 pups per dam were used as a control (10 litters each). On postnatal day (PN) 150, EO offspring were subdivided into EO and EO+mate groups (10 animals each), which were treated with water or mate tea [1 g/kg body weight (BW)/day, by gavage], respectively, for 30 days. The C offspring received water. On PN180, yerba mate treatment prevented BW gain and reduced total body fat, visceral fat and food intake in comparison with the EO group. Leptin and insulin signalling in the hypothalamus measured by Western blotting was reduced only in the EO group. Yerba mate treatment had a greater impact on insulin signalling normalization. In the liver, yerba mate treatment normalized antioxidant enzyme activities and, consequently, decreased lipid peroxidation, determined by malondialdehyde content. In addition, the steatosis level and the liver triglyceride content were also restored. Thus, for the first time, yerba mate was demonstrated to increase antioxidant defences and improve liver metabolism in adult rats that were overfed during lactation, possibly through improvements in the hypothalamic action of insulin. These findings may be important for the treatment of obesity-related disorders.

Physiological Variations

This preliminary study investigated for the first time the effect of roasted yerba mate (Ilex paraguariensis A. St. Hil.) tea on total creatine phosphokinase (CPK) in volunteers from the age of 50 years. Volunteers were randomly assigned to intervention (n = 3) and control (n = 3) groups. Treated subjects consumed mate tea for 28 days (500 mL/daily) and were submitted to five blood collection taken at intervals of seven days. It was observed a poor correlation between CPK level and yerba mate consumption. Results were also analyzed through cluster and principal component analyses. Treated and not treated subjects were not grouped into independent clusters which agreed with correlation analysis. Principal component analysis conferred partial discriminatory information about non-treated and treated groups. This study did not identify any influence of yerba mate consumption on total CPK concentration in physiological conditions. Larger sample studies should be addressed to detect significant small physiological variations in CPK values.
