ZAPATA, Bibiana et al. Antifungal activity, cytotoxicity and composition of essential oils from Labiatae family plants. Rev. Univ. Ind. Santander. Salud [online]. 2009, vol.41, n.3, pp.223-230. ISSN 0121-0807.

Introduction: Aspergillus spp. and Candida spp. are important cause of infections worldwide. Considering the resistance of these pathogens to some antifungal agents, there is greater need to search for new antifungal agents. Many extracts and essential oils isolated from plants have shown to exert antifungal effects in vitro. The aim of this study was to evaluate the antifungal, cytotoxic effect, and chemical composition of essential oils of family Labiatae. Materials and methods: Antifungal activity of twenty two essential oils from Labiatae family was evaluated against C. parapsilosis ATCC 22019, C. krusei ATCC 6258, A. flavus ATCC 204304 y A. fumigatus ATCC 204305, following EUCAST and M38-A standard protocols for yeast and filamentous fungi, respectively. Additionally, cytotoxic activity was evaluated on Vero cell line by colorimetric assay MTT. Essential oils was characterized by gas chromatography coupled to mass spectrometry. Results: The most active oil with all strains was obtained of Minthostachys mollis (MIC range 250 - 375 μg/mL). The essential oil from Hyptis mutabillis showed activity against A. fumigatus (GM-MIC = 396.8 μg/mL). These essential oils were not cytotoxic on Vero cells. The major components of essential oils from M. mollis and H. mutabillis were cis-piperitone epoxide and 1,8-cineol, respectively. Conclusions: Essential oils of H. mutabillis and M. mollis showed antifungal activity and they were not cytotoxic on Vero cells. Salud UIS 2009; 41: 223-230.
