The essential oils of the leaves, rhizomes, pods and seeds of Aframomum corrorima cultivated in the highlands of southern Ethiopia were obtained by hydrodistillation. The average moisture contents were 80.53% in leaves, 90.30% in rhizomes, 88.00% in pods and 14.19% in seeds when analyzed from fresh samples. The essential oils yield of leaves, rhizomes, pods and seeds were 0.46%, 0.69%, 0.83% and 4.30 % on a w/w dry basis, respectively. The pod and seed oil was analyzed by GC and GC/MS. Forty-two and 40 compounds from pods and seeds consisting of 95% and 99% of the total components were identified from the oils obtained. The major chemical constituents in pod oil were found to be gamma-terpinene (27.1 %), beta-pinene (15.4 %), alpha-phellandrene (8.5 %), 1,8-cineole (6.7 %) and p-cymene (6.4 %), while seed oil was predominated by 1,8-cineole (39.3 %) being followed by sabinene (10.4 %) and geraniol (6.8 %).
