Antimicrobial activity of Euphorbia nivulia leaf extract

Abstract

Aqueous alcohol extracts of the leaves of Euphorbia nivulia were investigated for antimicrobial activity. Nineteen different bacterial strains and two fungal cultures were used. The results indicate that the aqueous alcohol extracts were active at concentrations ranging from 3-12.5 μg/ml for Gram-negative and 12.5-200 μg/ml for Gram-positive bacteria. The activity was compared with known antibiotics such as streptomycin and nystatin.
