Composition and antimicrobial activity of the essential oil of<b><i>Acronychia pedunculata</i></b>(L.) Miq. from Vietnam

Abstract

The chemical composition and the antimicrobial activity of the essential oil isolated from aerial parts of Acronychia pedunculata (L.) Miq. from Vietnam are reported. Analysis was carried out by GC (RI), GC-MS and 13C NMR. Thirty-four compounds were identified, accounting for 92.8% of the oil. The major constituents were alpha-pinene (57.4%) and (E)-beta-caryophyllene (13.6%). The essential oil of A. pedunculata was shown to possess a broad spectrum of antimicrobial activity against various bacteria, particularly Salmonella enterica and Staphylococcus epidermidis.
