摘要: AbstractThe essential oil obtained by hydrodistillation from fresh needles of Pinus parviflora with the yield 0.16 % was analyzed gas chromatography/mass spectrometry and thirty-five compounds accounting for total 96.34 were identified. The rich in monoterpenes sesquiterpenes, dominated (+)-α-pinene (20.72 %), bornyl acetate (19.74 germacrene D (13.89 %) β-caryophyllene (11.74 %). Antibacterial activities extracted evaluated against seven food spoilage bacteria. results showed that effective most strains using agar disk diffusion method. broth microdilution bioassay indicated Bacillus subtilis sensitive strain minimum inhibitory concentration 3.75 mg/ml. Moreover, isolated tested antioxidant activities. It revealed prevailing hydroxyl radical scavenging ability over mannitol IC values 6.35 13.16 mg/ml th...
