Abstract: 【Objective】To clarify the antioxidant and antibacterial activities of essential oil from the fruit of Pugionium cornutum,and to provide reference for further development and utilization of essential oil products from the fruit of Pugionium cornutum.【Methods】The antioxidant activity of essential oil from the fruit of Pugionium cornutum was analyzed by measuring the scavenging of ·OH amd ·O2-and reducing capacities of different concentrations of the fruit of Pugionium cornutum diluents. At the same time,the antibacterial activity of essential oil from the fruit of Pugionium cornutum against Staphylococcus aureus,Escherichia coli,Bacillus subtilis,Listeria monocytogenes,Saccharomyces cerevisiae,Candida lipolitica and Aspergillus niger were detected.【Results】The antioxidative activity of essential oil from the fruit of Pugionium cornutum was strong,and it increased with the increase of the concentration of essential oil from the fruit of Pugionium cornutum. The scavenging ·O2- ability of essential oil from the fruit of Pugionium cornutum was better than vitamin C(VC)and 2,6-di-tert-butyl-4-methylphenol(BHT),but the reducing ability was lower than VC and BHT. The essential oil from the fruit of Pugionium cornutum had strong antibacterial activities against Staphylococcus aureus,Escherichia coli,Listeria monocytogenes,Bacillus subtilis,Aspergillus niger,Saccharomyces cerevisiae and Candida alpium. The minimum inhibitory concentration(MIC)against Staphylococcus aureus,Escherichia coli and Listeria monocytogenes was 40 mg/mL. The MIC was 30 mg/mL for Bacillus subtilis,8 mg/mL for Aspergillus niger,Saccharomyces cerevisiae and Candida albatum. The inhibition zone diameter of Listeria monocytogenes was 15.34 mm,which was high-sensitive type. The inhibition zone diameters of Escherichia coli,Aspergillus niger,Saccharomyces cerevisiae and Staphylococcus aureus were 14.29,14.00,11.26 and 10.20 mm,respectively,which was moderate-sensitive type. The diameters of inhibition zone of Bacillus subtilis and Candida albicans were 9.70 mm and 7.69 mm,respectively,which was low-sensitive type. The order of inhibitory effect of essential oil from the fruit of Pugionium cornutum on the tested bacteria was Listeria monocytogenes>Escherichia coli>Aspergillus niger>Saccharomyces cerevisiae>Staphylococcus aureus>Bacillus subtilis>Candida lipolitica.【Conclusion】The essential oil from the fruit of Pugionium cornutum had strong antioxidant activity and broad-spectrum antibacterial activity,which was a kind of natural plant material with good prospect for development and utilization.
