Chemical and Biological lnvestigation on Volatile Constituents of Pentadesma butyracea Sabine (Clusiaceae) From Benin

Abstract

The essential oils obtained by hydrodistillation of leaves, bark and mots of Pentadesm~ butyracea collected in Natitingou (Benin) were investigated bycapillary GC and GC/MS. Twenty-eight components, representing 97-99% of ails, were identified. The samples were exclusivelysesquiterpenic, dominated in ail cases by ~-caryophyllene (58.0- 75.0%) and a-humulene (10.1-14.2%); the leaf oil was characterized by a high content of a-copaene (14.2%). Finally, no significant antiradical activity (DPPH method) or inhibitory effect on the soybeen lipoxygenase activity could be observed
