Essential oil constituents of somePiper species

Abstract

The chemical compositions of essential oils of some Piper species were determined by capillary GC and capillary GC–MS. Elemol (11.5%) constituted the most abundant component of Piper nigrum leaf oil, β-Caryophyllene (13%) was the major constituent of P. attenuatum leaf oil, whereas β-cubebene (10%) was the major constituent of P. attenuatum berry oil. Cubebol (23.6%) was the major component of P. cubeba berry oil. Copyright © 1999 John Wiley & Sons, Ltd.
