Essential Oil Constituents of<i>Piper cubeba</i>L. fils. from Indonesia

Abstract

Abstract The chemical composition of the essential oil of ripe berries (11.8% v/w) and leaves (0.9% v/w) of Piper cubeba L. fils. (Piperaceae) was investigated by GC and GC/MS. Sabinene (9.1%), β-elemene (9.4%), β-caryophyllene (3.1%), epi-cubebol (4.3%), and cubebol (5.6%) were the main components of the berry oil. trans-Sabinene hydrate (8.2%), β-caryophyllene (5.0%), epi-cubebol (4.2%), γ-cadinene (16.6%) and cubebol (4.8%) were the main components of the leaf oil. No large qualitative differences were found in the composition between berry and leaf oil, although the berries contained a considerable amount of constituents in traces (< 0.05%) that were not found in the leaves. The principal difference was of a quantitative nature.
