Native or hydrolyzed starch and yerba mate extract (10 wt.% or 20 wt.%) films prepared by extrusion and compression molding were investigated. Native starch material (TPNS) exhibited lower water vapor permeability and higher Young's Modulus (E) compared to hydrolyzed starch matrix (TPHS) but decreases in strain at break (ε) and toughness (T). The incorporation of 10 wt.% of extract in TPNS led to greater E and ε and it resulted the most hydrophobic material. Conversely, TPHS with 20 wt.% of additive resulted the film with the highest ε and T, indicating a plasticizing effect of the extract in this concentration and system. All materials disintegrated after 10 weeks of burial, contributing to waste reduction. Biofilms containing yerba mate extract showed antioxidant activity and color changes in different pH, indicating their promising role as active and smart packaging for food, in accordance with the new trends for biodegradable and functional packaging.

Obesity is a global epidemic often associated with serious medical complications such as diabetes, hypertension and metabolic dysfunction-associated steatohepatitis. Considering the multifactorial nature of these diseases, medicinal plants could be a valuable therapeutic strategy as their phytoconstituents interact with multiple and relevant biological targets. In this context, Ilex paraguariensis emerges as a potential alternative to treat obesity and associated metabolic diseases since several studies have demonstrated its anti-inflammatory, anti-obesity and anti-diabetic effects.

The properties of two hybrid nanoarchaeosomes (hybrid nanoARCs) made of archaeolipids extracted from the halophilic archaea and combining the properties of archaeolipid bilayers with metallic nanoparticles are explored here. BS-nanoARC, consisting of a nanoARC loaded with yerba mate ( extract (YME)-biogenic silver nanoparticles (BSs), and [BS + BS-nanoARC], consistent of a BS-nanoARC core covered by an outer shell of BSs, were structurally characterized and their therapeutic activities screened. By employing 109 ± 5 µg gallic acid equivalents (GAEs) and 73.

Yerba mate (YM, ) is an economically important crop marketed for the elaboration of mate, the third-most widely consumed caffeine-containing infusion worldwide. Here, we report the first genome assembly of this species, which has a total length of 1.06 Gb and contains 53,390 protein-coding genes.

Yerba mate beverage is prepared from grown in South America, and its popularity still is increasing. The aim of this study was to show the differences in the content of antioxidant compounds between hot- and cold-prepared mate beverages. The antioxidant capacity of the infusions was tested using the Folin-Ciocalteu, ABTS, and DPPH assays.

The mini-cutting physiological condition is vital for the rooting process. For accurate interpretation, considering all mini-cutting responses in an experiment is necessary to identify significant rooting-biomarkers. The study investigates rooting-biomarkers during vegetative propagation, focusing on Ilex paraguariensis (yerba mate) clones of contrasting mini-cutting rooting performance as a case study (i.
