Abstract

The antimicrobial activity of different extracts of Plicosepalus acacia was tested against a number of microorganisms using agar diffusion method. The microorganisms used areStaphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. Ethyl acetate extract exhibited the highest activity against the tested Gram-positive bacteria (inhibition zones ranged from 24-25 mm) and also towards the fungus Candida albicans (25 mm inhibition zone). All the tested extracts were highly effective against the well-known highly resistant Gram-negative bacteria Pseudomonus aeruginosa, while the highest activity was observed with the chloroform extract (37 mm).

Summary

Introduction

Folk medicine is the method by which human beings have been trying to eliminate pain and promote good health since the beginning of time. Many of the methods used in folk medicine are ones that have been passed down from generation to generation. E-mail: Mistletoe is the common name for obligate hemiparasitic plants in several families in the order Santalales (Vaknin et al, 1996). These plants grow attached to and penetrating within the branches of a tree or shrub by a structure called the haustorium, through which they absorb nutrients from the host plant.
