Since the beginning of human civilization, medicinal plants have been used by mankind for its therapeutic value and even in modern times have formed the basis of many pharmaceuticals in use. The aim of the present study was to evaluate the antimicrobial activity of different extracts of Piper betle, Boerhavia diffusa, Oxalis corniculata, Centella a...

... incubation at 37˚C37˚C for 2 hrs until confirmation of the McFarland standard and then culture from broth were swabed on the Mueller Hinton Agar plate and implanted the standard antibiotic disc as the control along with the prepared discs (soaked with respective extracts) into the plates. The Mueller Hinton Agar plates were incubated at 37˚C37˚C for 24 to 48 hrs and observed the zone of growth inhibition (Figure 1). ...

... Cagri-Mehmetoglu et al. (2017) studied the antibacterial properties and minimum inhibition concentration of Microdesmis puberula, Hypoestis verticillaris, Icacina tricantha, and Enterolobium cyclocarpum against 21 different bacteria and reported the antibacterial activity and phenolic contents of four medicinal plants of Nigeria. Meghla et al. (2016) studied the antibacterial activity of some medicinal plants against Escherichia coli, Salmonella spp. and Staphylococcus aureus. ...
... Collected medicinal plants leaves were washed with tap water, ethanol and distilled water; and dried in sunshine and at oven (50˚C temperature). Then the dried samples were ground by mortar and pestle (Meghla et al., 2016;Ramchandran et al., 2012). The conical flasks were sterilized in the oven for 1 hour. ...
... The preparation of each solution was repeated and kept for 3 days at static conditions at room temperature. The extracts were filtered, centrifuged and evaporated (Meghla et al., 2016;Ramchandran et al., 2012) and were kept for further uses. ...
Screening of antibacterial activities of plants due to secondary metabolites is an authentic basis to look for a new drug. As a result of increasing demand for traditional treatments, scientists have look forward to search the efficacy of these so called ethnomedicinal plants and have to exchange with pharmacologists. An initiative of this, the antibacterial activity of Eclipta prostrata (L.) Mant. Azadirachta indica A. Juss., Aloe vera (L.) Burm. f. and Catharanthus roseus (L.) G. Don was studied against Escherichia coli and Staphylococcus aureus. Among four ethnomedicinal plants subjected to test antibacterial activities, Eclipta prostrata was found to act against both strains of bacteria whereas Azadirachta indica was effective against Escherichia coli only. DNA binding affinity of these medicinal plants was also studied by viscometry. No affinity between each medicinal plant extracts and isolated human cheek cell's DNA was observed.
