Constituents of the Essential Oils ofCinnamomum parthenoxylon(Jack) Nees from Vietnam

The essential oils obtained by steam distillation of the root bark and wood of Cinnamomum parthenoxylon (Jack) Nees growing wild in Vietnam were investigated by a combination of GC and GC/MS. More than 30 compounds in the root bark oil, and about 20 components in the wood oil have been identified. The main constituent of the root bark oil was benzyl benzoate (52.0%), whereas the wood oil consisted mainly of safrole (90.3%). The oil yield and the safrole content of the wood oil from different geographic regions in Vietnam showed little variation.
