The volatile components of the rhizomes of Aframomum alboviolaceum (Ridley) K. Schum. were extracted with hexane and analysed by GC–MS. The main constituents are (E)-labda-8(17),12-diene-15,16-dial (26, 33.1%), (+)-intermedeol (21, 24.1%), carotol (13, 8.3%), spathulenol (11, 5.8%), α-eudesmol (19, 2.3%), (Z)-β-farnesene (2, 2%), 10-epi-γ-eudesmol (15, 1.8%), β-biotol (14, 1.5%) and kongol (20, 1.2%). The diterpene (E)-labda-8(17), 12-diene-15,16-dial and the sesquiterpene (+)-intermedeol were isolated and fully characterized by mass spectra, 1H-NMR and 13C-NMR spectra.
