Abstract: To verify the bacteriostatic effect ofAloe vera extract, the filter paper method and solid dilution method were used to observe the bacteriostatic effect of the aloe juice on Bacillus subtilis,Escherichia coli , Staphylococcus aureus andAspergillus niger . The results showed that: the Aloe vera juice inhibited the selected bacteria growth obviously, but the antibacterial effect of filter paper was not obvious, the solid dilution method was better, the bacteriostatic effect of 100% Aloe vera juice was good, the bacteriostatic effect of 50% and 70% aloe juice were poor.
