Popis: The volatile constituents obtained by hydrodistillation of the aerial parts of Hyptis atrorubens Poit. growing in Martinique (F.W.I.: French West Indies) were analyzed by a combination of GC/FID and GC-MS. Plants from two different locations in Martinique (North and South) were studied. For the north location, two preparation methods were studied: hydrodistillation in 3L or 20 L reactors and steam distillation. Sixty components representing between 87.7% and 93.2% of the essential oil GC/FID chromatogram total area were identified. The most abundant compounds were caryophyllene oxide (from 5.0 to 31.5%), β-caryophyllene (from 4.7 to 32.6%), palmitic acid (from 2.0 to 9.5%), spathulenol (from 1.5 to 8.5%), α-copaene (from 4.5 to 6.9%), 2-tridecanone (from 0.0 to 6.1%) and phytol (from 2.3 to 4.8%). By comparison with the literature describing a first chemotype rich in Germacrene D and a second chemotype rich in limonene and estragole, in our study Germacrene D was only present at 1.1 and 2.1% in th...
