Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° Spécial (Juillet 2006) . - pp. 129-133 Titre : The biological activities of 20 nature identical essential oil constituents Type de document : texte imprimé Auteurs : Robyn L. Van Zyl, Auteur ; Sammy T. Seatlholo, Auteur ; Sandy F. Van Vuuren, Auteur Année de publication : 2013 Article en page(s) : pp. 129-133 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Nature  identical  essential  oil  constituent  (-)-α-bisabolol  Geraniol  (±)-linalool  (E-  &  Z-)-(±)-nerolidol  (-)-citronellal  Trans-geranyl  acetate  Linalyl  acetate  (±)-α+β-thujone  (+)-carvone  (-)-fenchone  (-)-menthone  (-)-pulegone  Carvacrol  Eugenol  (+)-α-pinene  (+)-β-pinene  γ-terpinene  p-cymene  1,8-cineole  (+)-limonene  Antimicrobial  activity  Antimalarial  activity  Antioxidant  activity  Toxicity Résumé : Twenty nature identical essential oil constituents from seven structural groups were tested for antimalarial, antimicrobial, antioxidant and toxicity properties. The compounds displayed antimalarial activity (IC50 values ranging from 0.9 to 1528.8 μM) with varying toxicity (IC50 values ranging from 5.5 to 1358.4 pM). The data indicates that (-)-pulegone, (E- & Z-)-(±)-nerolidol, linalyl acetate and (+)-α-pinene have the most potent antimalaial activity. Carvacrol (MIC values ranging from <1.66 to 13.3 mM) followed by geraniol (MIC values: 19.5-51.9 mM) displayed the broadest spectrum of antimicrobial activity. The least toxic of the tested compounds, eugenol, was the only compound with antioxidant activity comparable to ascorbic acid. The results demonstrate that the 20 compounds individually display variable biological activity, although further research is required to determine how they may interact when combined.
