Antifungal activity and toxicity studies of flavanones isolated from aerial parts.

[Asteraceae] is traditionally employed in Northwestern Argentina for fungal infections treatment. We report the antifungal activity guided isolation and identification of substances from aerial parts of this species, both individually and in combination with fluconazole (FLU), against strains. Two antifungal flavanones were identified as naringenin (NAR) and pinocembrin (PIN).
