The leaf oil of Goniothalamus gabriacianus (Baill.) Ast collected from Ha Tinh province in May 2006 was isolated by steam distillation with oil yield of 0.15% and analyzed by Capillary GC and GC/MS.
Thirty five components have been identified accounting for more than 99.4% of the oil. The major constituents of this oil appeared to be a-pinene (44.5%), b-pinene (22.1%) and b-phellandrene (12.0). Predominant minor compounds included a-phellandrene (4.7%), b-myrcene (3.4%), (E)-b-ocimene (2.8%), bicyclogermacrene (2.5%), b-caryophyllene (1.5%) and g-terpinene (1.2%).
