✦ Synopsis
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( ),12-diene-15,16-dial (26, 33.1%), ()-intermedeol (21, 24.1%), carotol (13, 8.3%), spathulenol (11, 5.8%), a-eudesmol (19, 2.3%), (Z)-b-farnesene (2, 2%), 10-epi-g-eudesmol (15, 1.8%), b-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, 1 H-NMR and 13 C-NMR spectra. # 1997 by John Wiley & Sons, Ltd.
