Fungi are cosmopolitan organisms that grow in and adapt to a vast number of substrates and environments, and that can cause diseases in humans and animals, as well as in crops. The vast area and diverse geographical characteristics of Argentina, with the consequent climatic diversity make the country an important source of biological resources suitable for the search of new compounds. The aim of the present study was to describe the antifungal activity of extracts of Parastrephia quadrangularis… Expand
Antifungal activity of phytotherapeutic preparation of Baccharis species from argentine Puna against clinically relevant fungi.
The traditional use of both Baccharis species as an antimicrobial against commercial products resistant fungal strains was validate, principally against dermatophytes fungi such as T. rubrum, T. canis, and M. gypseum. Expand

Antimicrobial phenylpropanoids from the Argentinean highland plant Parastrephia lucida (Meyen) Cabrera.
The antimicrobial effect found in the crude drug was associated with mixtures of phenylpropanoids, including prenyl and phenethyl esters of caffeic and cinnamic acids, which support at least in part the traditional use of the plant as local antiseptic. Expand
Effect of zinc compounds on Fusarium verticillioides growth, hyphae alterations, conidia, and fumonisin production.
Zn compounds have advantages compared to other antifungal compounds, in particular, they are non-toxic for the organism in appropriate amounts, and could be studied further as potential fungicides in agriculture. Expand
Antifungal activity of extracts of extremophile plants from the Argentine Puna to control citrus postharvest pathogens and green mold
The aim of this work was to screen extremophile plants from the Argentine Puna in order to select species with antifungal activity against Penicillium digitatum and Geotrichum citri-aurantii, two very important fungal species causing citrus postharvest disease. Expand
Antimicrobial activity in methanolic extracts of several plant species from northern Argentina.
Thirty-nine native plant species were collected from the provinces of Chaco and Formosa, in northern Argentina, and were screened for antimicrobial activity, finding that some extracts were able to reduce the initial number of viable counts by at least one order of magnitude in 10 hours, indicating the possible presence of bactericidal components.
