Antibacterial Activity of Some Plant Extracts Used in Folk Medicine

Abstract

In the present work, selected plants were screened for their potential antibacterial activity. For evaluating antibacterial activity, both aqueous and organic solvent methanol was used. The plants screened were Ocimum sanctum, Jatropha gossypifolia, Boerhavia diffusa, Azadirachta indica, Solidago virgaurea, and Commelina benghalensis. The antibacterial activity was assessed against six bacterial strains--Pseudomonas testosteroni, Staphylococcus epidermidis, Klebsiella pneumoniae, Bacillus subtilis, Proteus morganii, Micrococcus flavus. Agar disc diffusion method and Agar ditch diffusion method were used to study the antibacterial activity of all these plants. Ps. testosteroni and K. pneumoniae were the most resistant bacterial strains. A. indica showed strong activity against tested bacterial strains. Therefore, we conclude that A. indica may prove to be a promising agent, and further exploration into this compound should be performed to determine its full therapeutic potential. In addition, its leaf extract can also be used as a lead molecule in combating the diseases caused by the studied bacterial strains.

Chemo-profiling, Antioxidant Potential and Ionomic Analysis of Cichorium intybus L.

“…33 It has also been considered that plants and their phytochemical extracts holds great assurance to be used in future medicines as they contain possible sources of antiviral, anti-tumoral and anti-microbial agents. 34,35 Polyphenols were found to be important for research and gains a lot of attention since they were found more effective on human health. 36 Polyphenols and flavonoids are responsible for prevention of various diseases caused by free radicals.…”

A Comparative antimicrobial analysis of Tridax procumbens L. various extracts on waterborne bacterial pathogens

“…The present result proves that acetone extract can be employed for the development of formulation for the purification of water from bacteria like Escherichia coli, Vibrio cholerae from diseases like cholera and diarrhoea (Aniel and Naidu, 2011). As it is cleared from the previous literature that extract of organic solvent are much better than aqueous extract for formulation purpose (Nair et al, 2005).…”

Antitubercular and Phytochemical Investigation of Methanol Extracts of Medicinal Plants Used by the Samburu Community in Kenya

“…42 (125 mm) and concentrated using a rotary evaporator (Laborota 4000, SN 090816862, Germany) in a water bath set at 40 °C [8]. The extract was dried in a dessicator over anhydrous CuSO 4 . The powdered residues were transferred into vials and stored pending analysis.…”

“…Natural products, either as pure compounds or as standardized plant extracts, provide unlimited opportunities for new drug leads because of the unmatched availability of chemical diversity [3]. Scientific interest in medicinal plant has burgeoned in recent times due to increased efficiency of new plant derived drugs and rising concerns about the side effects of modern medicine, and hence the need to look for new molecular structures as lead compounds from the plant kingdom [2,4].…”
