Study on the Antibacterial Activity of Plantago asiatic L.

Objective: To compare the antibacterial ability of extracts that was extracted by different dissolvent from plantain.
Methods: Tap-water, ultra-pure water, ethanol, methanol, ether, petroleum ether, chloroform and benzene were used to extract the antibacterial ingredients of plantain at room temperature; three kind bacteria were medium containing different extracts, and Spectrophotometry assays were performed to measure the antibacterial ability of extracts. Results: The antibacterial ability of extracts according to C,D,E,G,H （P<0.05）priority was ingredient extracted. Ingredients extracted by Tap-water, ultra-pure water display non-antibacterial ability（P>0.05）. Conclusion: Organic solvents were more effective as dissolvent to extract antibacterial ingredients of plantain.
