文摘

The chemical composition of essential oil obtained by hydrodistillation from the dried fruits of Chaenomeles speciosa was analyzed by GC–MS. Forty compounds, constituting about 85.13 % of the total oil, were identified. The main constituents were β-caryophyllene (12.52 % ), α-terpineol (5.41 % ), terpinen-4-ol (4.56 % ) and 1,8-cineole (4.31 % ). The antimicrobial activity of the oil was evaluated against 10 microorganisms using disc diffusion and broth microdilution methods. The essential oil was found to show a broad spectrum of antimicrobial activity against all the tested bacterial strains. The essential oil had more sensitivity to gram-positive than gram-negative bacteria.
