| Résumé : |
The composition of the essential oil from leaves and branches of Beilschmiedia pendula growing wild in Costa Rica was determined by capillary GC-FID and GC/MS.
Sixty eight and 67 compounds were identified in the leaf and branch oils respectively corresponding to about 84.3% and 96.7% of the total amount of the oils. The leaf oil consists mainly of monoterpene hydrocarbons (27.4%), sesquiterpene hydrocarbons (33.0%) and oxygenated sesquiterpenes (16.3%). The major components of the leaf oil were b-pinene (10.4%), b-caryophyllene (8.6%), a-pinene (7.9%) and bicyclogermacrene (7.2%). The branch oil consists mainly of sesquiterpene hydrocarbons (59.3%) and oxygenated sesquiterpenes (24.9%). The major components of the branch oil were b-caryophyllene (17.3%), b-selinene (9.1%), bicyclogermacrene (8.9%), a-cadinol (5.8%) and spathulenol (4.6%). |
