Barreto, Auteur Article en page(s) : pp. 451-452 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Mouriri cearensis Melastomataceae Essential oil composition (Z)-3-hexenol Index. décimale : 646 Résumé : The chemical composition of the leaf oil of Mouriri cearensis Hub was examined by gas chromatography (GCFID) and gas chromatography/mass spectrometry (GC/MS).
Fifteen compounds comprising 92.9% of the total peak area were identified.
Alcohols (80.6%) and esters of aliphatic acids (7.5%) were the major components identified with (Z)-3-hexenol (66.5%), linalool (8.8%) and (Z)-3-hexenyl butyrate (5.4%) being the most prominent.DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Chemical composition of the essential oil from leaves of mouriri cearensis huber [texte imprimé] / Nilce V.

The oil obtained was examined by gas chromatography (GC-FID) and gas chromatography/ mass spectrometry (GC/MS).
Thirteen compounds comprising 95.9% of the total peak area were identified.
The main constituents identified were spathulenol (47.7%) and caryophyllene oxide (18.3%).DEWEY : 665 ISSN : 1041-2905 En ligne : http://www.jeoronline.com/archive/detail/42#top [article] Volatile components of the essential oil from bauhinia ungulata L.
