ABSTRACT
The composition of the essential oils of the leaves and spikes of Piper bisasperatum Trel. (Piperaceae) obtained by hydrodistillation were investigated by GC-MS. The main constituents of the leaves oil were the sesquiterpenes germacrene D (30.7percent) Beta caryophyllene (9.5 percent) and gamma-elemene (5.9 percent), together with the monoterpene beta-pinene (5.5 percent). The main constituents of the spikes (flowers and fruits) were the monoterpenes beta-pinene (17.5 percent), alpha-pinene (14.0 percent) and the sesquiterpenes germacrene D (19.5 percent), beta-caryophyllene (7.9 percent) and ylangene (7.6 percent). The C6-C1 compounds benzyl benzoate (0.3 percent) and benzaldehyde (< 0.1 percent) were identified for the first time in the genus Piper
