Constituents of the Rhizome and Root Oils of Alpinia breviligulata Gagnep. from Vietnam

ABSTRACT

The volatile constituents of the rhizome and root oils of Vietnamese Alpinia breviligulata Gagnep. were investigated by high resolution GC and GC/MS. More than 35 components have been identified. The rhizome oil consisted mainly of β-pinene (11.1%), borneol (7.0%), (β-caryophyllene (8.0%), α-humulene (7.9%) and caryophyllene oxide (10.5%). The major components of the root oil were 1,8-cineole (6.0%), borneol (5.5%), fenchyl acetate (8.8%), β-caryophyllene (7.5%), α-humulene (10.8%) and caryophyllene oxide (13.0%).
