Abstract:
Taking Ficus tikoua Bur. as test material,based on the single factor experiment,the ethanol reflux extraction technology of antibacterial substance from Ficus tikoua Bur. was optimized by orthogonal experiment.Bacteriostatic effect of the extracts was detected by Oxford Cup method against Staphylococcus aureus,Escherichia coli,Shigella sonnei, antibacterial effect of Candida albicans,and the effect of heat and ultraviolet radiation on its antibacterial activity were also investigated.The results showed that the optimum extraction process of ethanol reflux were 65% ethanol,solid-liquid ratio 1∶10 g?mL-1,0.5 hours heating in 75 ℃ water bath.The antibacterial effect of the extracts on Staphylococcus aureus was the best,and Candida albicans had no antibacterial effect.With the increase of the concentration of the extract,its antibacterial effect was enhanced,and it had a certain stability to the heat and ultraviolet radiation.
