title: Potential antimicrobial effects of pharmacognostic drugs.
abstract: Pharmacognostic aspect, in treating of natural medicinal materials and medicinal of natural origin, is presented by very complex group of analytical and applicative methods. They are applied by means of identification, purities and quality of natural medicinal materials of vegetal, animal or mineral origin, more precisely of pharmacognostic drugs. A great number of drugs and their isolated products show the antimicrobial activities. The chemical substances, which are present in drugs, are currier of antimicrobial activities manifested by action on different bacteria, fungus, parasites and even viruses. The whole series of methods for analyzing of antimicrobial effects of drugs and the medicines in general are treated by scientific discipline microbiology. In order to complete the pharmacognostic analyses of drugs and there medicinal products, the microbiological analyses take a very important role. The antimicrobial and antifungal effects of series of plant materials, of pharmacognostic drugs against the large number of bacteria and fungus Candida have been carried out. The drugs we analyzed were treated from their chemical point of view and that is the presence of: coumarins, mucus and anthraquinones. The contents of these substances in plant material were analyzed by method of thin layer chromatography that was published preliminary. The antimicrobial effects of analyzed drugs were determinate by using dilution method in antimicrobial analyses which have been carried out with decocts of drugs.
