| Abstract: | Objective：To explore the antibiotic activity of polysaccharide from Herba Houttuynia cordata.Methods： Polysaccharide in fresh Herba Houttuynia cordata was extracted by water extraction and alcohol precipitation and ultrasound-assistet extraction;the antibiotic activity of the extract was measured by agar-diffusion assay.ResultsConclusions：The result showed that the extract had inhibitory effect on Escherichia coli and Staphyloccocus aureus,and the ultrasound-assisted extraction of polysaccharide had better antibiotic activity than water extraction. |
