ANTIBACTERIAL PROPERTIES OF BRYOPHYLLUM PINNATA LEAF EXTRACT AGAINST STREPTOCOCCUS SPP. AND KLEBSIELLA SPP.
Abstract
The study was on the evaluation of antimicrobial property of Bryophylum pinnata. Healthy fresh
samples of the leaves of Bryophyllum pinnata were airdried in a room (to retain the green colouration)
for six (6) weeks; the dried leaves were blended into powder. The extracts of Bryophyllum pinnata were
made from the dried leaves and tested against Klebsiella and Streptococcus. The result from
antimicrobial sensitivity testing of Bryophyllum pinnata leaf extracts revealed that both extracts
(ethanol and water) had inhibitory effects against the pathogenic microorganisms tested. The plant
extracts showed a dose-dependent inhibition of the microorganisms. The highest concentration of 100%
extracts had the highest inhibition as the concentration was reduced, the zone of inhibition also reduced.
Based on the result of this research, further work should be done to purify and characterize these
bioactive substances in B. pinnatum to identify the main active ingredient in a bid to transform this into
a drug and the dose be known.
