Chemical composition and antimicrobial activity of the volatile oil from baccharis articulate (Lam.) pers. / Euclésio Simionatto in The journal of essential oil research, Vol. 20 n°4 (Juillet/Août 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 20 n°4 (Juillet/Août 2008) . - pp. 366-368 Titre : Chemical composition and antimicrobial activity of the volatile oil from baccharis articulate (Lam.) pers. Type de document : texte imprimé Auteurs : Euclésio Simionatto, Auteur ; Vinicius Ilha, Auteur ; Anderson S. Mallmann, Auteur Année de publication : 2008 Article en page(s) : pp. 366-368 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Baccharis  articulata  Asteraceae  Essential  oil  composition  β-pinene  Enantiomeric  distribution  Antimicrobial  activity Résumé : The essential oil obtained from aerial parts of Baccharis articulata (Lam.) Pers. from Rio Grande do Sul, Southern Brazil, was analyzed by GC, GC/MS, and chiral phase gas chromatography (CPGC). Twenty-nine compounds representing ca 86.1 % of the oil were identified. The main compounds in the oil were β-pinene (39.0%), cis—-guaiene (9.8%), γ-muurolene (5.8%), limonene (4.8%), α—pinene (4.5%), α—gurjunene (4.4%) and spathulenol (4.2%). The antimicrobial activity of the oil was evaluated against seven microorganisms using the broth microdilution method. The oil displayed antimicrobial activity against Gram-positive and Gram-negative microorganisms (MIC=2.5 mg/mL).

Forty-two compounds representing ca 98.0% and 90.5% were identified in the oils of samples A and B, respectively. Sesquilavandulyl acetate (7.6—24.1%), sesquilavandulol (8.2—24.3%) and α-gurjunene (20.0–20.5%) were the major components. The antimicrobial activity of the oils, sesquilavandulol acetate and sesquilavandulol is also reported.
