The leaf oil of Uvaria grandiflora Roxb. ex Hornem collected from Ha Tinh province, Vietnam, in May 2007 was isolated by steam distillation to give oil yield 0.1% and analyzed by Capillary GC and GC/MS. Thirty three components have been identified accounting more than 94.2% of the oil respectively. The major constituents of this oil appeared to be bicyclogermacrene (35.7%), β-caryophyllene (13.9%) and (Z)-b-ocimene (10.7%).
Less predominant constituents included β-elemene (6.6%), germacrene D (6.0%), α-humulene (3.9%), bicycloelemene (2.5%), (E)-b-ocimene (2.3%), α-amorphene (1.8%), β-selinene (1.7%), and a-cubebene (1.0%). All the other components were in concentration of less than 0.1-0.9%.Downloads
