Abstract: This study aimed to analyse the chemical composition of essential oils from Diphasia klaineana fruits, its fractions and evaluate their antibacterial activity. The GC-MS analysis and agar disc diffusion and micro-broth dilution methods were carried out. A total of 43 constituents were identified in the essential oil from fruits of Diphasia klaineana (F_R) and the major compounds were β-elemol (30.23%), sabinene (9.28%), guaiol (5.12%), (E)-β-ocimene (5.11%) and δ-elemene (3.53%). The F_R1 and F_R3 fractions collected after one hour and after three hours were rich in hydrocarbon monoterpenes and showed bactericidal and bacteriostatic activities, respectively. No activity was found with F_R5, F_R7 and F_R9 fractions. Therefore, fractional distillation may be an interesting process to upgrade the antibacterial activity of D. klaineana fruits essential oil againt Staphylococcus aureus.
