Volatile constituents of rhizomes and leaves of Alpinia allughas roscoe

Abstract The GC and GC/MS analyses of the oils from the rhizome and leaves of Alpinia allughas led to identification of 22 and 42 constituents, respectively. The major constituents of the rhizome oil were β-pinene (55.3%) and α-pinene (9.7%) whereas in the leaf oil β-pinene (25.5%), 1,8-cineole(23.3%) and α-humulene (9.7%) were major. The unique feature is the dominant presence of two pinenes (rhizome (65%) and leaf (30.9%)) unlike other species of Alpinia.
