Phytochemistry And Evaluation Of Some Plant Extracts On Streptococcus Mutans And Candida Albicans:- Okeke, Obianuju C
ABSTRACT
The upsurge in the prevalence of side effects of
many synthetic antimicrobial agents and incidence of multidrug resistant
bacteria has spurred scientists on the research for plant based antimicrobial
of therapeutic potentials. Azadirachta indica and Psidium guajava present such
potential of high medicinal value. These plants are used in Nigeria
traditionally as condiments and for treatment of various ailments such dental
plague . The phytochemical composition of Azadirachta indica and Psidium
guajava showed the presence of Tannin, Alkaloid, Saponin and Flavonoid. Aqueous
and ethanol extracts of Azadirachta indica and Psidium guajava leaves were
screened for antibacterial activity against Candida albican and Streptococcus
mutans. Both extracts were found to exhibit selective inhibition against the
isolates. The diameter zones of inhibition exhibited by the extracts were
between 2 ± 0.01 - 10 ± 0.10 mm. The Minimum Inhibitory Concentration (MIC)
determined by the agar diffusion method was between 10.00 and 2.50 mg/ml-1.
Ethanol extracts showed more 'inhibitory effect compared to the aqueous
extracts. Results obtained show that the extracts of Azadirachta indica and
Psidium guajava possess some level of antibacterial activities against
Steptococcus mutans and Candida albicans.
