In Vitro Activities of Panduratin A against Clinical Staphylococcus Strains

In vitro antistaphylococcal activities of panduratin A, a natural chalcone compound isolated from Kaempferia pandurata Roxb, were compared to those of commonly used antimicrobials against clinical staphylococcal isolates. Panduratin A had a MIC at which 90% of bacteria were inhibited of 1 mu g/ml for clinical staphylococcal isolates and generally was more potent than commonly used antimicrobials.
