Adeniyi, Auteur Année de publication : 2010 Article en page(s) : pp. 189 - 192 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Kyllinga  erecta  Cyperaceae  Essential  oil  composition  α-humulene  Farnesyl  acetate  1,8-cineole  Chemotype  Antimicrobial  Activity Index. décimale : 646 Résumé : The investigation of the essential oils of the aerial part and rhizomes of Kyllinga erecta by capillary gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) led to the identification of 31 and 49 compounds respectively. The oil of the aerial parts had 1,8-cineole (10.5%), α-humulene (21.7%), farnesyl acetate (11.2%), β-caryophyllene (9.9%) and selin-11-en-4-ol (8.9%) as the major components, while the rhizome oil was dominated by 1,8-cineole (12.7%) and cyperene (11.34%) and E,E-farnesol (5.5%). This analyses, especially that of the rhizome oil, suggest another chemotype of K. erecta from the known predominant cyperene-type.

A total of 31 components were identified, accounting for 99.7% of the oil composition. Menthone (50.9%), pulegone (19.3%) and 1,8-cineole (11,9%) were the major constituents of the oil. The oil was screened against Gram + and Gram - bacteria and found to be very active against Bacillus subtilis, Micrococcus kristinae, Staphylococcus aureus and Staphylococcus epidermidis with minimum inhibitory concentrations ranging from 0.039 to 0.078 pg/mL.

Volatile constituents of the leaf oils of callistemon salignus from two provinces in South Africa / O. O. Oyedeji in The journal of essential oil research, Vol. 22 N° 6 (Novembre/Décembre 2010) 

Public ISBD [article]  in The journal of essential oil research > Vol. 22 N° 6 (Novembre/Décembre 2010) . - pp. 613-615 Titre : Volatile constituents of the leaf oils of callistemon salignus from two provinces in South Africa Type de document : texte imprimé Auteurs : O. O. Oyedeji, Auteur ; A. O. Oyedeji, Auteur ; F. O. Shode, Auteur Année de publication : 2011 Article en page(s) : pp. 613-615 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Callistemon  salignus  ‘Rubra’  Myrtaceae  Essential  oil  composition  1,8-cineole  α-pinene Index. décimale : 646 Résumé : Essential oil was isolated from the leaves of Callistemon salignus ‘Rubra’ collected from two Provinces using hydrodistillation method. Analyses of the compound were done using GC and GC/MS. Between 16–22 compounds were identified, accounting for 90.1–98.5% of the oil samples. The characterized oil samples show a high percentage of oxygen-containing monoterpenes in all the localities. 1,8-Cineole was found to be the main component in all the samples being present in the range of 44.4–85.4%. Others prominent compounds of the oils were α-pinene (6.2–27.8%), α-terpineol (tr-6.8%) and E-(β)-ocimene (tr-6.7%).
