Abstract The essential oils obtained by hydrodistillation of the rhizomes of Alpinia conchigera and Alpinia latilabris were analysed by capillary GC and GC–MS; 50 compounds were identified in A. conchigera rhizome oil, among which 30 have not been detected previously. The major chemical class was terpenoids, with β ‐bisabolene (28.9%), 1,8‐cineole (15.3%) and β ‐caryophyllene (10.0%) the major components. A. latilabris rhizomes yielded 33 identified constituents, the majority terpenoids, but the oil was clearly dominated by methyl ( E )‐cinnamate (89.5%). Copyright © 2005 John Wiley & Sons, Ltd.
