Screening of local medicinal plant extracts against multi drugs resistance bacteria

Abstract

Multi Drugs Resistance (MDR) bacteria are mostly resistant to most of antibiotics, this leads to several severe infections and diseases. Thus the desire of new antibiotic sources are required which direct to the screening of new medicinal plants and use against MDR pathogenic bacteria. In our study, the antibacterial activity of three different plant extracts are utilized against pathogenic bacteria in-vitro to treat the infection and disease cause by pathogenic bacteria. The extracts were isolated from Mallotus philippensis, Silybum marianum and Stachys parviflora Benth in four different solvents extracts and were tested against eight pathogenic MDR bacterial strains (Brucella abortus, Escherichia coli, Enterobacter sakazakii, Proteus vulgaris, Klebsiella pneumoniae, Providencia stuartii, Pseudomonas aeruginosa (gram negative) and Staphylococcus aureus (gram positive) through well diffusion and disc diffusion. It was found that the extracts of selected plants showed maximum activity against all bacterial strains. The recorded zones of inhibition were 8.0-26.33mm for methanolic, 6.0-17.66mm for chloroform extracts and 8.01-2.33mm for ethyl acetate extracts. So, it is cleared from the results that the tested plant extracts have great potential as antibacterial compounds against bacteria. However, further research is required to isolate and identify the active ingredients are vital for further pharmacological evaluation. Also screening of these plants for Anticancer and Anti-diabetic activity will be significant.

Phytochemical Analysis and Biological Activity of Three Stachys Species (Lamiaceae) from Romania

“…One of the most important properties of plants is their action on the human body [7][8][9][10]. These aspects are highlighted especially through study of the levels and types of bioactive compounds they contain [11][12][13][14] and/or on their biological activity [15][16][17][18].…”
