The Antibacterial Activity Of Leaf Extracts Of Jatropiza Curcas And Eupliorbia Heterophylla
ABSTRACT
Four extracts from Nigerian plants, Euphorbia heterophylla and Jairopha
curcas were screened for antibacterial activities using disc diffusion and
micro dilution broth assays. Ethanol and Aqueous extracts of each of the plants
were tested against four microorganisms consisting of two gram positive
bacteria (Staphylococcus aureus and Streptococcus faecalis) and two gram negative
bacteria (Escherichia co/i and Pseudomonas aerugiaosa). The antibacterial
activity was measured by the diameter zone of inhibition and minimum inhibitoiy
concentration (MIC).All the extracts exhibited moderate broad spectrum
antibacterial activities against the microorganisms except ethanol extract of I
curcas which had no inhibitory activity on the organisms. The diameter of zone
of inhibition range from 10mm-i 5mm at 2000mg/ml of crude extract peidisc. The
MIC values were between I25mg/ml-l000mglml. The activities of some of the crude
extracts were comparable to the reference antibiotics (Tezracycli,ie and
Ainpici/lin) at standard concentration per disc. These findings are discussed
towards the development of cheap, culturally acceptable standardized herbal
medicines and as sources of novel macules for development of broad spectrum
antibacterial agents.
