The response surface methodology optimizes in the study. The ultrasonic extraction process of polysaccharide from Lycopus lucidus Turcz. was optimized by using response surface methodology. The vitro antibacterial activity of roughly purified L. lucidus polysaccharide on Escherichia coli, Bacillus subtilis, Bacillus licheniformis and Staphylococcus aureus. The optimal extraction conditions were determined as followed: liquid-solid ratio: 40.73 mL/g; ultrasonic power: 542.70 W; under the optimized extraction conditions, the extraction yield of L. lucidus polysaccharide was 8.59% (close to the theoretical value of 8.55%). In addition, L. lucidus polysaccharide showed very strong antibacterial activities E. coli, S. aureus and quite significant antibacterial activities on B. licheniformis.
