Abstract: OBJECTIVE To investigate the bacteriostatic action of ethanol extracts and salt extracts of the fruit of Phyllanthus emblica L. on the microflora of the digestive tract, and determine its best antimicrobial part, so as to carry out its bacteriostatic effect. METHODS The bacteriositatic action of ethanol extracts and salt extracts of the fruit of Phyllanthus emblica L. was determined by cup plate method, and their MICs were measured by doubling dilution method. The bacteriostatic test of the active part to the microflora on the digestive tract was determined by macro broth dilution method. And their MICs were measured. RESULTS The test by comparing the inhibition zone diameter and colony growth conditions indicated alcohol extracts and salt extracts of Phyllanthus emblica L. had strong inhibitory effect, the best site for the antibacterial was ethyl acetate portion. The salt extracts had the better bacteriostatic action. The MICs showed not only ethanol extracts but also salt extracts had inhibitory effect, and had better effect on the anaerobe. CONCLUSION Antibacterial effect of salt extracts was better than the alcohol extract, and ethyl acetate portion had better inhibitory action on gastrointestinal microflora.
