Public ISBD [article]  in The journal of essential oil research > Vol. 20 N°1 (Janvier/Fevrier 2008) . - pp. 75-78 Titre : Chemical composition and antimicrobial activity of essential oils of eugenia chlorophylla (Myrtaceae) Type de document : texte imprimé Auteurs : Maria Elida A. Stefanello, Auteur ; Armando C. Cervi, Auteur ; Izabel Y. Ito, Auteur Année de publication : 2008 Article en page(s) : pp. 75-78 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Eugenia  chlorophylla  Myrtaceae  Essential  oil  composition  β-caryophyllene  Caryophyllene  oxide  Globulol  1-epi-cubenol  T-muurolol  α—cadinol  Antimicrobial  activity Résumé : The chemical composition of essential oils of stems, leaves (at vegetative and flowering stages) and flowers of Eugenia chlorophylla O. Berg., (Myrtaceae) obtained by hydrodistillation, were analyzed by capillary GC and GC/MS. Thirty-four components were identified, representing more than 80% of total oil. The major components were β-caryophyllene (flowers −12.8%), caryophyllene oxide (stems—17.2%), globulol (stems—16.5%; leaves—22.5% at vegetative stage and 18.9% at flowering stage), 1-epi-cubenol (stems −10.9%), epi—α—muurolol (stems—16.8%) and α—cadinol (stems—12.1%; flowers −10.1%). The oils were evaluated against 20 strains of bacteria (Gram-positive and Gram-negative) and yeasts. All oils showed mild to moderate antimicrobial activity associated mainly with Gram-positive bacteria and yeasts.

Chemical composition and cytotoxic activity of essential oil from myrcia laruotteana fruits / Maria Elida A. Stefanello in The journal of essential oil research, Vol. 23 N° 5 (Septembre/Octobre 2011) 

Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 5 (Septembre/Octobre 2011) . - pp. 7-10 Titre : Chemical composition and cytotoxic activity of essential oil from myrcia laruotteana fruits Type de document : texte imprimé Auteurs : Maria Elida A. Stefanello, Auteur ; Dilamara Riva, Auteur ; Edésio L. Simionatto, Auteur Année de publication : 2012 Article en page(s) : pp. 7-10 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Myrcia  laruotteana  Myrtaceae  Essential  oil  composition  α-bisabolol  α-bisabolol  oxide  B  Antiproliferative  activity Index. décimale : 646 Résumé : The essential oil isolated by hydrodistillation from unripe fruits of Myrcia laruotteana Camb. (Myrtaceae) was analyzed by GC and CG/MS. Forty-four components were identified, representing around 83% of total oil. The major components were α-bisabolol (23.6%) and α-bisabolol oxide B (11.5%). The cytotoxicity of the oil and of a fraction rich in α-bisabolol was tested in vitro against U251 (glioma), UACC-62 (melanoma), MCF-7 (breast), NC1-ADR/RES (ovarian-resistant), 786.0 (kidney), NCI-H460 (lung), PC-3 (prostate), OVCAR-3 (ovarian), HT-29 (colon) and K562 (leukemia) human cancer cells and against VERO (no cancer cell). The oil exhibited antiproliferative activity against all cell lines (TGI < 100 μg/mL), with exception of NCI-H460 cell line (TGI > 125 μg/mL). The highest activity of the oil was observed against U251 (TGI 20.46 μg/mL), 786.0 (TGI 20.74 μg/mL), UACC-62 (TGI 26.98 μg/mL) and PC-3 (TGI 27.63 μg/mL) cell lines. The fraction rich in α-bisabol showed a similar activity profile. It was most active against OVCAR-3 (TGI 8.58 μg/mL) and 786.0 (TGI 8.74 μg/mL).

St. Hil. (Magnoliaceae), collected in four seasons, were analyzed by capillary GC and GC/MS. Altogether 52 components were identified. The oils were characterized by predominance of cyclic sesquiterpenes. The main components were linalool, trans-β-guaiene, germacrene D, germacrene B, spathulenol, caryophyllene oxide, viridiflorol and α-eudesmol. The content of individual components was variable during the year. All oils were screened against several strains of bacteria and yeasts, using the agar well-diffusion technique. The antimicrobial activity of oils showed strong dependence with the season. Significant activity was found for oils obtained in the spring and summer.
