Assessment Of The In-Vitro Anti-Bacterial Activity Of Pterocapus Santalinoides And Ageratum Conyzoides:- Ajah, Stephen O
ABSTRACT
The antibacterial and phytochemical screening
of A. conyzoides and P. santalinoides were carried out to find the medicinal
importance of these plants among the people of Ikwuano L.G.A in Ahia State.
Agar well diffusion method was used to measure the zone of inhibition and broth
dilution assay to assess the Minimum Inhibitory Concentration (MIC) of the
antibacterial activity testing of the methanol extracts of these plant extracts
against selected susceptible organisms. The four test bacteria used were
Staphylococcus aureus (A TCC 25923), Escherichia coli (ATCC 25922), Pseudomonas
aeruginosa (A TCC) and Salmonella typhi. The methanol extract of A. conyzoides
produced a diameter of zone of inhibition of 12.00mm against Staphylococcus
aureus, 00.00mm against Pseudomonas aeruginosa, 00.00mm against Salmonella
typhi while Methanol extract of P. santalinoides produced a diameter of zone of
inhibition of 14.00 mm against Staphylococcus aureus, 10.00mm against
Pseudomonas aeruginosa, 11.00mm against Salmonella typhi. Both plants extract
had no effect on Escherichia coli. The phytochemical screening of these plants
leaves showed the presence of alkaloids, tannins, Saponins, phenol and
flavonoids. The research work suggests the use of A. conyzoides and P.
santalinoides in herbal medicine.
