Essential Oils of Two Portuguese Endemic Species of Lavandula as a Source of Antifungal and Antibacterial Agents

Chemical investigations of L. stoechas subsp. luisieri and pedunculata essential oils were analyzed by GC-MS, the antimicrobial activity was performed against bacteria fungi isolated from food sources. The cytotoxicity oil in NHDF cells using MTT method. According to results, main compounds trans-α-necrodyl acetate (40.2%), lavandulyl (11%), trans-α-necrodol (10.4%), while fenchone (50.5%) camphor (30.0%) oil. antifungal confirmed with MIC values ranging 1.2 18.7 µL/mL; for bacteria, it ranged 4.7 149.3 µL/mL. Both Lavandula species tested showed low or equal MBC/MFC oil, revealing greater efficacy activity. revealed cytotoxic effects (30 ± 2% cell viability) at all concentrations tested.
