Resumen:
The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of Baccharis darwinii were analyzed, for first time, by GC and GC/MS. Forty components were identified, representing 97.2% of the total oil. The major components were limonene (47.1%), thymol (8.1%), 4-terpinelol (6.4%), sabinene (5.7%), alpha-pinene (4.6%), alpha-terpineol (3.7%), myrcene (3.6%) and carvacrol (3.2%). The in vitro evaluation of the anti-insect properties showed promising insecticide activity against Ceratitis capitata, Mediterranean Fruit Fly (LD50 19.85 to 31.01 µg/fly for males and females respectively at 72 h) and repellent activity against Triatoma infestans, Chagas disease vector (average repellence 92%). In addition, the oil exhibited strong antifungal activity against yeast and dermatophytes of clinical relevance including some fungus such as Candida spp and Trichophyton spp with MICs values between 62.5 and 125μg/mL.
