Abstract The volatile constituents of the leaves and flowers of Alpinia speciosa and Alpinia purpurata growing wild in North Brazil were analysed by GC–MS. The main constituents identified in the leaf oil of A. speciosa were limonene (25.1%), terpinen‐4‐ol (22.7%) and γ‐terpinene (17.4%). The oil obtained from flowers of A. speciosa was dominated by 1,8‐cineole (23.1%), terpinen‐4‐ol (20.4%) and sabinene (14.5%). The major components identified in the leaf oil of A. purpurata were 1,8‐cineole (21.8%), β‐pinene (15.3%) and ( E )‐methyl cinnamate (12.9%). The oil obtained from flowers of A. purpurata was dominated by β‐pinene (27.8%) and α‐pinene (16.9%). Copyright © 1999 John Wiley & Sons, Ltd.
