Exploring the Phytochemical Composition and the Bioactive Properties of Malbec and Torrontés Wine Pomaces from the Calchaquíes Valleys (Argentina) for Their Sustainable Exploitation.

Hydroalcoholic extracts from Malbec and Torrontés wine pomaces ( L.) originating from the high-altitude vineyards of Argentina's Calchaquí Valleys were characterized. Total phenolics, hydroxycinnamic acids, orthodiphenols, anthocyanins, non-flavonoid phenolics, total flavonoids, flavones/flavonols, flavanones/dihydroflavonols, and tannins were quantified through spectrophotometric methods, with the Malbec extract exhibiting higher concentrations in most of phytochemical groups when compared to Torrontés.

Argentinean Puna Plants with In Vitro Antioxidant and Anti-Inflammatory Activities as a Potential Nutraceutical.

Parastrephia lucida (Compositae), Tessaria absinthioides (Compositae), and Ephedra multiflora (Ephedraceae), three plant species from the Argentinean Puna (3600 m.a.s.

Effect of Wine Wastes Extracts on the Viability and Biofilm Formation of and Strains.

In this work, we intended to inhibit the biofilm synthesis and the metabolism of Gram-positive and Gram-negative bacteria using two highly available wastes (stem and marc) obtained after the manufacturing of Torrontes wine at Cafayate, Argentina. Wine wastes contain a significant amount of bioactive compounds, mainly phenolic compounds, which makes them a potential source of compounds with beneficial properties to human health, as they could inhibit the virulence of pathogenic bacteria or protect the tissue against oxidative stress. Marc and stem extracts of Torrontes wine were evaluated for their ability to inhibit the metabolism and biofilm production of and strains.

Inhibition of pro-inflammatory enzymes by medicinal plants from the Argentinean highlands (Puna).

Ethnopharmacological Relevance: Human groups in the Argentinean Andes highlands (Puna) selected native plants as anti-inflammatory agents. The indications of use are mainly to relieve pain, as infusions, ethanolic extracts or plasters.

Aim Of The Study: The objective of the study was to assess the effect of hydroalcoholic extracts from native highland plants as anti-inflammatory agents according to the traditional indications of use.
