[Kinetics of the anti-staphylococcal activity of bakuchiol in vitro (author's transl)].

The growth curve of Staphylococcus aureus in a liquid medium with and without bakuchiol, the main component of Psoralea corylifolia Linn., has been studied for in vitro evaluation of the antibacterial activity. The dynamics of the antibacterial action has also been studied by finding the generation time and number of generations of the microbial growth before stationary phase is reached. This study of the growth curve of the test bacteria gives in general an accurate method of evaluating the in vitro antibacterial activity of drugs with exact mathematical implications, besides serving also as a means for studying the kinetics as well as the mode of antibacterial action.
