Antimicrobial Activities of Leaf Extracts of Pilostigma thonnigii (Camel Foot Tree) and Vernonia amygdaline (BITTER LEAF) on Clinical Isolates (Staphylococcus aureus and Escherichia coli)”:-Chukwuemeka, Oluchi H
ABSTRACT
The
aim of this work is to determine the antimicrobial activities of leaf extract
of Piliostigma thonngii and Vernonia
amydalina. This study was carried out by drying the leaves at room
temperature and was grounded using apestle and motar into smaller particles.
100grams of the powdered sample was then stored in airtight container. This study was carried out to evaluate the
antibacterial effect of Pilostigma
thonnigii and Vernonia amygdalina
on Staphylococcus aureus and E.coli. The plants were identified and
ethanolic and aqueous extraction of the dried leaves samples were done using
standard procedures. Antibacterial activity of the extracts was tested invitro
against Staphylococcus aureus and E.coli using agar diffusion method. The pattern of inhibition
varied with plant extract, solvent used for extraction and test organisms.
Ethanol extracts showed the highest zone of 37mm of Pilostigma thonnigii against Staphylococcus
and highest zone of 35mm by V.
amygdalina against E coli. For
the water extract Pilostigma thonnigii
showed high zone of 27mm than that of V.
amygdalina which showed 16mm. it was
also observed that Staphylococcus had
the lowest minimum inhibitory concentration against Pilostigma thonnigii and V.
amygdalina respectively. From this
work, it has been noted that the leave of Pilostigma
thonnigii and Vernonia amygdalina have
antibacterial properties.
