Summary: | SynopsisSalvia somalensis Vatke, a wild sage native of Somalia, has been studied with the aim of assessing the potential cosmetic application of its essential oil, recovered from fresh aerial parts by solvent-free microwave extraction - SFME. To evaluate the efficiency and reliability of this ecofriendly procedure, the recovery of the essential oil was also processed by conventional hydrodistillation (HD) and the results compared. The essential oils obtained by both SFME and HD were analysed by gas chromatography-mass spectrometry using apolar and polar capillary columns. The essential oil recovered by SFME was submitted to an odour evaluation that revealed peculiar olfactive characteristics interesting in alcoholic male perfumery and body detergents.In vitro cytotoxicity assays were carried out using NCTC 2544 human keratinocytes as target cells. The oil displayed slight cytotoxic effects, which were three orders of magnitude lower than those found for sodium dodecyl sulphate positive control. The promising results in terms of chemical composition, scent and safety seem to indicate this essential oil as an interesting potential functional ingredient useful in a cosmetic context. ResumeSalvia somalensis Vatke, une plante sauvage native de la Somalie a eteetudiee dans le but d'evaluer le potentiel cosmetique de son huile essentielle, obtenu des parties aeriennes fraiche, avec un procede d'extraction sans solvant par micro-ondes - SFME. Pour determiner le rendement et la fiabilite de ce procedeecocompatible, la recuperation de l'huile essentielle a ete aussi conduite par hydrodistillation (HD) et les resultats obtenus ont etes compares. Les huiles essentielles obtenues par SFME et HD ont ete analysees avec GC-MS au moyen d'une colonne polaire et d'une apolaire. L'huile essentielle recuperee par SFME dans l'objectif d'etude de ses proprietes olfactives, presente des caracteristiques olfactives particulieres, interessantes pour un emploi dans la parfumerie alcoolique masculine et dans des detergents pour le corps. On a realise des tests de cytotoxicitein vitro sur une lignee cellulaire de keratinocytes humains NCTC 2544. L'huile montre une faible cytotoxicite, inferieure de trois ordres de grandeur par rapport au temoin positif, dodecylsulfate de sodium. Les resultats obtenus pour ce qui concerne la composition chimique, le parfum et la securite toxicologique semblent indiquer que cette huile essentielle peut presenter un interet comme nouvel ingredient cosmet |
