The antimicrobial potential of selected ethnomedicinal plants in traditional healers of Silent valley, Palakkad district of Kerala, India against venereal diseases causing pathogens. Twelve medicinal plants and their parts were collected from the various places of Silent Valley, Kerala, India. These plant parts were dried and mixed with different kinds of solvents respectively hexane, chloroform, methanol and water. In this study, six microbial strains were selected, in which five bacterial and a fungal strain. Among the bacterial strains, two strains were gram positive and three strains for gram negative bacteria. Totally, twelve medicinal plant parts mixed with various solvents were treated against the selected pathogenic organisms. Among them, methanolic extract of A. occidentate, C. indica, H. rosa-sinensis and M. oleifera exhibited excellent antibacterial activity than other parts of plants and standard drugs. As well as, methanolic extract of H. rosa-sinensis showed good antifungal activity against C. albicans. While,the least inhibition was noted with aqueous extract of C. indica against S. aureus. The MIC ranges from 0.78μg/ml to 50μg/ml and MBC/MFC 1.52μg/ml to 50μg/ml. The methanolic flower extract of H. rosa-sinensis has showed effective zone of inhibition against all the pathogens, particularly N. gonorrhoeae (30 mm) and C. albicans (26mm), than other extracts and standard drugs. Therefore, we concluded that, flower extract had potential therapeutic activity against venereal diseases. This research will be helpful to discover the new therapeutic drug molecule in Pharmaceutical sectors.
