Abstract:
Objective To determine the main components of SZ herbal disinfectant and to observe its inactivation efficiency on microorganism in suspension. Methods The spectrophotometer examination, neutralizer screening trial, bacteria count trial, phage plaque count trial and cells infection test had been used to determine contents of ursolic acid in SZ herbal disinfectant and the disinfection efficacy. Results The ursolic acid contents in original SZ disinfectant reached 436.43 ?g/ml and decreased by 8.07% after a year of deposit. Treated by disinfectant for 5 min and 1∶5 dilution solution for 10 min, the Staphylococcus aureus (SA) and Escherichia coli (EC) in suspension could be killed with the efficiency of 100%. Treated with SZ disinfectant and the dilution solution (1∶50) respectively, the Candida albicans could be killed with the efficiency of 90.97% and 51.10%. Treated with the dilution solution for 3 min, the f2 bacteriophage and PV could be reduced by 100% and 9.00 log. Conclusion With the main component of ursolic acid, the SZ herbal disinfectant is a kind of natural disinfectant. It has a satisfactory inactivation efficacy on bacterial vegetative form and virus.
