Abstract

The essential oil from the leaves of the Amentotaxus yunnanensis collected in Hoang Su Phi, Ha Giang province was obtained by hydrodistillation using a Clevenger apparatus and the yield of the essential oil was 0.01% from air-dry material. By using GC/MS analysis 50 constituents were identified, accounting for 88.96% of the essential oil. The main constituents were α-pinene (21.91%), kaur-16-ene (13.03%), α-calacorene (9.42%), δ-cadinene (6.23%) and β-caryophyllene (4.9%). This is the first study on the chemical constituents of essential oils from the leaves of Amentotaxus yunnanensis in Vietnam.


Keywords: essential oil, Amentotaxus yunnanensis, α-pinene, kaur-16-ene, α-calacorene, δ-cadinene.
