Abstract
Two labdane diterpenes were isolated from the seeds and the rhizomes o f Aframomum alboviolaceum (Ridley) K. Schum (Zingiberaceae) and identi fied by GC-MS, H-1-, and C-13-NMR as (E)-labda-8(17),12-diene-15,16-di al (1) and (E)-8beta,17-epoxylabd-12-ene-15,16-dial (2). A third minor compound could be the methyl (E)-14xi,15-epoxylabd-8(17), 12-dien-16- oate. The simultaneous occurrence of these three molecules has been me ntioned only in one other species of the same genus, Aframomum daniell ii (1).
