摘要:

对百香果汁的抑菌活性进行初步研究。结果表明百香果原汁对大肠杆菌、金黄色葡萄球菌、热带假丝酵母和黑曲霉均有一定抑制作用;其乙醇- 丙酮提取物对大肠杆菌、金黄色葡萄球菌、热带假丝酵母和黑曲霉也有一定的抑制作用,MIC 分别为125、250、500mg/mL 和500mg/mL;其环己烷提取物对大肠杆菌和金黄色葡萄球菌有一定的抑制作用,MIC 都为250mg/mL,而对热带假丝酵母和黑曲霉无抑制作用。

Abstract:

A preliminary antibacterial evaluation of passion fruit juice was performed in this paper. Passion fruit juice had strong inhibitory effect on Escherichia coli, Staphylococcus aureus, Candida tropicalis and Aspergillus niger. The ethanol-acetone (1:1, V/V) extract from the juice also had inhibitory effect on E. coli, S. aureus, C. tropicalis and A. niger with minimum inhibitory concentrations (MICs) of 125, 250, 500 mg/mL and 500 mg/mL, respectively. The cyclohexane extract from the juice had inhibitory effect on E. coli, S. aureus with a MIC of 250 mg/mL but no inhibitory effect on C. tropicalis and A. niger.

Key words: passion fruit juice, antibacterial activity, ethanol-acetone extract, cyclohexane
