✦ Synopsis
The composition of the essential oil isolated from the seeds of Aframomum melegueta (Roscoe) K. Schum. by hydrodistillation was characterized by means of gas chromatography (GC) and gas chroma-tography±mass spectrometry (GC±MS). A total of 27 compounds constituting 98.6% of the volatile oil were identi®ed. Two sesquiterpene hydrocarbons: humulene and caryophyllene made up 82.6% of the volatile oil, whilst their oxides amounted to a further 9.0%. Seventeen other mono-and sesquiterpenes accounted for only 1% of the volatile oil. Five non-terpenoids were detected in trace amounts only (50.2%). Of the 27 constituents identi®ed, 12 are reported as components of A. melegueta for the ®rst time.
