Screnning photochemical and evaluation of antimicrobial activity of Catarantus Roseus (l.) G. Don, Justicia Pectoralis Jacq. and Escoparia Dulcis

The present work purpose is to determinate the antimicrobial action or the Scoparia dulcis L., Justicia pectoralis Jacq., and Catharanthus roseus (L.) G. Don, through the method proposed by Mitscher. This method is based in the bacterial susceptibility measured in vitro. It consists on using the interest extract with the microorganisms of election in agar environment and complete asepsis conditions. Catharanthus roseus (L.) G. Don is the species that presents the greatest number of alkaloids, followed by Justicia pectoralis Jacq. and Scoparia dulcis L, which has the highest number of Tannins and Cardiotonic Glycosides and the next, is Catharanthus roseus (L.) G. Don and Justicia pectoralis Jacq. Which present a similar content of Tannins and Cardiotonic Glycosides? Regarding to the steroids the 3 studied species present a similar quantity and only Justicia pectoralis Jacq. has light quantity of Flavonoids. The raw standardized extract of Scoparia dulcis L. shows antibiotic action (bacteriostatic action), about Pseudomona aeruginosa from a concentration of 62.55 ug/ml, this one is the minimum inhibitory concentration CMI. It also presents antibiotic activity with fungicide power in the microorganism Candida albicans in a concentration of 31.25 ug/ml; this is the CMI.
