The essential oils isolated by hydrodistillation from the fresh leaves, stems and rhizomes of Piper
lolot C. DC. have been analyzed for the first time by a combination of GC and GC/MS. The oils contained
more than 35 compounds, of which 25 constituents could be identified according to their chromatographic
retention indices and mass spectra. The main constituent of the oils was ?-caryophyllene (26.1-30.9%). The
rhizome oil contained bornyl acetate (10.0%) as second major component.
