The essential oils of Lantana camara L-occurring in North Brazil

The essential oils of aerial parts of three samples of Lantana camara L. co llected at different places in the Amazon Region were obtained by hydrodist illation and analysed by GC-MS. The main constituents found in the oil of l eaves and thin branches of a specimen collect in the State of Amapa (sample A) were limonene (16.5%), alpha-phellandrene (16.4%), germacrene-D (13.2%) , beta-caryophyllene (10.8%) and sabinene (8.9%). The major components iden tified in the oil of leaves and thin branches of a specimen collected in th e State of Roraima (sample B) were germacrene-D (28.4%), germacrene-B (9.1% ) and beta-caryophyllene (5.6%). The specimen collected in the State of Par a (sample C) furnished oils from leaves plus thin branches and flowers, sep arately. Both were dominated by gamma-curcumene + ar-curcumene (27.6%; 31.9 %), alpha-zingiberene (19.2%; 15.5%) and alpha-humulene (10.7%; 9.5%), resp ectively. Copyright (C) 1999 John Wiley & Sons, Ltd.
