Abstract
Momordicosides were the active ingredient of Momordica Charantial L.and had antibacterial effects.The different antibacterial concentrations of momordicosides on Escherichia coli,bacillus subtilis,and staphylococcus aureus were judged by the growth curves.The minimum inhibitory concentrations(MIC) of momordicosides were detected by agar dilution methods.The best momordicosides antibacterial conditions of Escherichia coli,and staphylococcus aureus were detected by orthogonal experimental design methods.The results showed that momordicosides almost had no inhibition on the growth of Aspergillus niger.50,100,150,200mg/mL concentration of momordicosides could inhibit the growth of Escherichia coli,bacillus subtilis and Staphylococcus aureus.And the strongest inhibition concentration was 150mg/mL.The MICs of momordicosides on Escherichia coli,and staphylococcus aureus were both 30mg/mL,and on bacillus subtilis 40mg/mL.The best momordicosides inhibitory conditions of Escherichia coli and staphylococcus aureus were temperature at 40℃,inhibition time of 20h,and pH for 6.0.
