Anti-Candida activity of Brazilian medicinal plants

Citral and carvone chemotypes from the essential oils of Colombian Lippia alba (Mill.) N.E. Brown: composition, cytotoxicity and antifungal activity

“…Aligiannis et al (2001) suggested a classification for plant materials, based on MIC results, as follows: strong inhibitors, MIC up to 0.5 mg/ mL, moderate inhibitors, MIC between 0.6 and 1.5 mg/ mL, and weak inhibitors, MIC above 1.6 mg/mL. Based on these criteria, Duarte et al (2005) indicated a strong activity of L. alba oil against C. albicans, with an MIC of 0.06 mg/mL, while MIC of the positive control nystatin is 0.05 mg/mL. On the other hand, Borges-Argáez et al (2007) have suggested that a MIC value of 100-200 µg/mL can be considered acceptable for plant material.…”

“…alba occurs in various regions of Colombia (Durán et al 2007) and although the antifungal activity of some essential oils of this plant have been evaluated in other countries (Duarte et al 2005, Hennebelle et al 2006, in Colombia the biological activities of the L. alba chemotypes have not yet been fully elucidated. The aim of this study was to evaluate the chemical composition, cytotoxic effect and antifungal activity of essential oils of L. alba, as well as some of their components, from two regions of Colombia.…”

Interference of heating on the antimicrobial activity and chemical composition of Origanum vulgare L. (Lamiaceae) essential oil

“…Some compounds found in O. vulgare essential oil have shown antimicrobial properties in laboratorial media and/or foodstuffs, including carvacrol (FERRARA; MONTESANTO;CHIANTESE, 2003;SALGUEIRO et al, 2003), p-cymene (BURT, 2004, myrcene (DUARTE et al, 2005), γ-terpinene (MARÍN et al, 2004) and limonene (FABIO et al, 2003). Carvacrol has been known as a marker of antimicrobial activity in essential oils, deserving a prominent scientific interest as a natural antimicrobial agent (CHUN et al, 2005;FARIAS-ALVES et al, 2003).…”
