ABSTRACT
The
antimicrobial activity and phytochemical analysis on the leaves of
Caricapapaya, Citrus sinensis. Citrus paradisi and Vernonia atnygdalina was
carried out. The four plant species were found to contain alkaloid, saponin,
tannins, flavonoid and phenols in varying proportions. The concentration of the
phytochemicals are as follows: alkaloid of paw-paw (1.11 ± 0.02%), saponins
(0.53 ± 0.04%) tannin (0.43 ± 0.4%), flavonoid (0.67 ± 0.01%) and phenols (0.91
± 0.03%), for grape alkaloid content was (0.31 ± 0.05%), saponins (0.19 ±
0.01%). tannins (0.25 ± 0.01%), flavonoid (0.36 ± 0.02%), phenol (0.52 ± 0.04%)
In orange, alkaloid was (0.23 ± 0.01%), saponin (0.23 ± 0.01%), tannin (0.15 ±
0.01%), flavonoid (0.33 ± 0.01), phenol (0.59 ± 0.07%) For bitter leaf,
alkaloid (1.31 ± 0.03%), saponin (1.15 ± 0.01%). flavonoid (0.71 ± 0.02%),
tannin (0.43 ± 0.01%), phenol (1.15 ± 0.01%). The plant contain more alkaloid
than other phytochemical. The anti-microbial activity of the ethanolic and
aqueous extracts of leaves of the plants were tested against four
microorganism. Klebsiella pneumonia. Salmonella pullorum, Enterobacter
aerogenes and Proteus vulgaris. The susceptibility of the microorganisms was
determined using the disk diffusion method. The leaf extract of these plants
inhibited the growth of these pathogens. The minimum inhibitory concentration
was analyzed using agar well diffusion method with values ranging between 50
mg/ml and 200 mg/ml against all the clinical isolates. There were variations in
the lowest concentrations of the different plant extracts that caused
inhibitions against the various microorganisms.
