STUDIES ON ANTIMICROBIAL SPECTRUM OF ROSE PETALS AGAINST BACTERIAL PATHOGENSD. H. TAMBEKAR AND S. S. MANKARAbstract The total 27 varieties of roses petals were studies for their antibacterial activities. Out of these, petals of 19 varieties were found moderate to strong antibacterial against all the tested bacteria and the remaining 8 varieties were weak antibacterial. The Pseudomonas aeruginosa was found to be highly sensitive against all the 27 rose varieties with maximum zone of inhibition (30 mm). The Bacillus coagulans, E.coli, Shigella flexetteri, Staphylococcus epidermidis, Salmonella typhi were moderately and Enterobacter aerogenes, En terococcus faecalis, Klebisella pneumoniae, Proteus vulgaris, Staphylococcus aureus, Salmonella typhimurium were weakly sensitive. The Pseudomonas aeruginosa, which were resistance to most of standard antibiotics, found sensitive to almost all varieties of rose petals. In most of the rose varieties, the antibacterial activities were more or less same with tested rose petals. Enterococcus faecalis and Staphylococcus aureus were resistant to five varieties and Escherichia coli, Bacillus coagulans; Proteus vulgaris, Klebsiella pneumoniae and Salmonella typhi were resistant to one variety each. Therefore petals of these rose varieties can be used against infection caused by these organisms that may decrease the use of antibiotics and its ill effects. Thus this natural cure can be partially replaced the use of antibiotics.
