Van Vuuren, Auteur Année de publication : 2013 Article en page(s) : pp. 48-51 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Salvia  muirii  Lamiaceae  Biological  activities  Essential  oil  composition  α-pinene  1,8-cineole  Limonene  Antimicrobial  activity  Anti-inflammatory  activity  Antimalarial  activity  Antioxidant  activity  Toxicity Résumé : The essential oil of Salvia muirii L. Bol., a species indigenous to southern Africa was obtained by hydrodistillation (0.5%, v/f.w.) from the aerial parts and analyzed by GC and GC/MS. Thirty-nine components representing 98% of the oil were identified. The oil was dominated by monoterpene hydrocarbons (53%) and oxygen-containing monoterpenes (36%) with 1,8-cineole (23%), α-pinene (22%) and limonene (12%) being the major components. The oil exhibited potent antimalarial (IC50: 6μg/mL) and antibacterial activity especially against Klebsiella pneumoniae and Bacillus cereus with MIC values of 6 and 9mg/mL, respectively. The oil exhibited poor anti-inflammatory and antioxidant activity. The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide toxicity assay revealed that the essential oil of S. muirii should be used with caution as it displayed some degree of toxicity against the transformed human kidney epithelial cells (IC50: 3μg/mL).
