ABSTRACT A steam-distillated essential oil (1% yield) obtained from the dried leaves of Piper acutifolium (Piperaceae) was analyzed by capillary GC and GC/MS. The major constituents identified were: (E)-β-ocimene (8.1%), α-copaene (6.1%), allo-aromadendrene (6.0%), α-cadinene (6.7%), δ-cadinene (6.8%), myristicin (4.2%) and dillapiole (5.9%). The oil was evaluated for biological activity against Callosobruchus maculatus (a stored grain insect pest). There was no effect on mortality; however, a significant decrease in oviposition was observed.
