allows the increase of antihypertensive and antioxidant activities in apple cider.

This study aimed to investigate the impact of the malolactic fermentation (MLF) carried out by on antihypertensive and antioxidant activities in cider. The MLF was induced using three strains of . The modification in phenolic compounds (PCs) and nitrogen organic compounds, antioxidant, and antihypertensive activities were determined after MLF.

Geoffroea decorticans fruit extracts inhibit the wnt/β-catenin pathway, a therapeutic target in cancer.

Geoffroea decorticans (chañar) is commonly used for culinary and medicinal purposes in rural communities. The aim of this work was to chemically characterize three Geoffroea decorticans extracts and determine their capacity to modulate the wnt/β-catenin pathway. This signaling pathway plays a key role in embryonic development but its overactivation leads to cancer cell growth.

Active sesquiterpene lactones against Leishmania amazonensis and Leishmania braziliensis.

Seventeen sesquiterpene lactones (SLs) isolated from five species of the tribe Vernonieae were evaluated for their in vitro activity against promastigotes of Leishmania amazonensis and Leishmania braziliensis. Additionally, a quantitative structure activity relationship has been made, since all these natural compounds were found to have potent to mild antileishmanial properties. The most active compounds against L.

Effect of seasonal variations and collection form on antioxidant activity of propolis from San Juan, Argentina.

Propolis was included in the Argentine Food Code as a functional food. The chemical parameters and antioxidant properties of propolis samples from the same colonies of Apis mellifera in San Juan (Cuyo region, Western Argentine) were compared every month for 1 year using two collection methods. Chemical parameters were analyzed by the spectrophotometric method and fingerprinting using high-performance liquid chromatography with ultraviolet detection.
