Antimicrobial screening of Mentha piperita essential oils.

Essential oils of peppermint Mentha piperita L. (Lamiaceae), which are used in flavors, fragrances, and pharmaceuticals, were investigated for their antimicrobial properties against 21 human and plant pathogenic microorganisms. The bioactivity of the oils menthol and menthone was compared using the combination of in vitro techniques such as microdilution, agar diffusion, and bioautography. It w...

Assessment Report on Mentha X Piperita L., Folium

Supercritical CO2 extraction of mentha (Mentha piperita L.) at different solvent densities

The chemical composition of mentha essential oil and mentha extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC–MS. The menthol content was also determined spectrophotometrically. The predominant compounds in the essential oil and in the CO2 extract obtained at 100 bar were L-menthon and menthole but at higher pressures (from 150 to 4...

Avaliação de Ferramentas para Controle Automatizado de Versões de Artefatos e Requisitos de Software

The control of all the artifacts generated by a development team tends to be a great challenge in software development process. Such a need starts in the moment that the project begins, that is, in the preliminary requirements elicitation phase. From this moment on, any change not duly registered can reflect in failure at the end of the project. Having tools that allow the control of the artifa...
