Chemical composition and antimicrobial activities of the essential oil of hypericum cordatum (Vell.Conc.) N. robson (Hypericaceae) / Angela M. Ladeira in The journal of essential oil research, Vol. 21 N° 6 (Novembre/Décembre 2009) 

Public ISBD [article]  in The journal of essential oil research > Vol. 21 N° 6 (Novembre/Décembre 2009) . - pp. 558-560 Titre : Chemical composition and antimicrobial activities of the essential oil of hypericum cordatum (Vell.Conc.) N. robson (Hypericaceae) Type de document : texte imprimé Auteurs : Angela M. Ladeira, Auteur ; Giovanna B. da Silva, Auteur ; Ludmila Raggi, Auteur Article en page(s) : pp. 558-560 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Hypericum  cordatum  Hypericaceae  Essential  oil  composition  α-pinene  Myrcene  Limonene Index. décimale : 646 Résumé : The volatile constituents of the fresh materials of Hypericum cordatum were isolated by hydrodistillation and analyzed by GC and GC/MS. The leaves produced 0.04% of a yellowish essential oil and the flowers did not. The main components of the oil were myrcene (40.18%), a-pinene (16.40%), and limonene (12%). The antibacterial activities of the oil against Saccharomyces aureus and Escherichia coli and the anti-fungal activities of the oil against the fungi Cladosporium cladosporioides and C. sphaerospermum were evaluated. The oil showed an antibacterial activity against the bacteria S. aureus and anti-fungal activity against the two fungi.
