Abstract: Objective: To analyze the chemical composition and evaluate the antibacterial activity of Hanyuan Zanthoxylum bungeanum seed oil. Methods: The chemical composition of Hanyuan Zanthoxylum bungeanum seed oil was determined by gas chromatography-mass spectrometry (GC-MS). Its minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were also determined by agar diffusion method and tube double dilution method. Results: The major components of Hanyuan Zanthoxylum bungeanum seed oil were D-limonene (26.55%), linalool (22.11%), linalyl acetate (14.71%) and β-pinene (7.39%). Meanwhile, the essential oil revealed strong antibacterial activity. Its MIC and MBC were 1.25 mg/mL and 5.0 mg/mL against Staphylococcus aureus, and 2.5 mg/mL and 20.0 mg/mL against Escherichia coli, respectively. Conclusion: Hanyuan Zanthoxylum bungeanum seed oil has excellent antibacterial activity so that it can be used as a resource of natural food preservatives.
