Antibacterial Activity of Thai Herbal Compress Ball from Community Enterprise Groups in Roi Et Province

Abstract

The aim of this study was to evaluate antimicrobial effects of Thai herbal compress ball collected from community enterprise groups in Roi Et Province. Fourteen of the balls were used to liquid and fine powder using low temperature dehydration process and used to test the antimicrobial activity. There were gram positive bacteria (S. aureus and CNS) and gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa,  Acinetobacter baumanii and Proteus mirabilis) for agar disc diffusion and broth dilution were the analysis method and determination of levels for preparation to enter minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) by broth dissolveion method. Results, Preliminary study of antibacterial activity, liquid form SP2 only inhibited S. aureus with MIC 11±S.D. of inhibition zone using agar disc diffusion method. The best bacterial inhibitor was SL2. It showed antibacterial activity against extracted to liquid and fine powder using low temperature dehydration process for MIC and MBC test. The results were not different for either liquid or powder extracts.
