Abstract
ABSTRACT Examination of the foliage oils of 25 specimens of Prumnopitys ferruginea identified ten sesquiterpene hydrocarbons (δ-elemene, α-cubebene, α-copaene, β-cubebene, germacrene-D, β-selinene, bicyclogermacrene, germacrene-A, δ-cadinene and γ-cadinene), the rare sesquiterpene ketone, acorenone, seven diterpene hydrocarbons (rimuene, beyerene, pimaradiene, sandaracopimaradiene, phyllocladene, kaurene and abietatriene) and a diterpene alcohol (Sβ-hydroxyisopimarene). Terpene levels were highly variable. β-Elemene, cis-calamenene and cadina-1,4-diene were detected as artefacts of aging of extracts. Some of the components showed antimicrobial activities against Bacillus subtilis and Trichophyton mentagrophytes, and cytotoxic activity against monkey kidney cells.
