A Study of the Antibacterial Effect of Euphorbia hirta L. Bud Extracts against Escherichia coli

Abstract

Methanol, ethanol, dimethyl sulfoxide and Aqueous extracts of buds of Euphorbia hirta L. have been evaluated for antibacterial effect against Escherichia coli. Antibacterial effect examined by disc diffusion method. Maximum in vitro inhibition was scored in methanol or aqueous extracts of bud of Euphorbia hirta L. which showed inhibition diameter of 20 mm against Escherichia coli, followed by dimethyl sulfoxide extract of the same plant leaf with inhibition diameter of 15 mm. Moderate inhibition of E. coli was found in ethanol extract of Euphorbia hirta with inhibition diameter of 13 mm. Bud extract of Euphorbia hirta possess antibacterial particles soluble in different solvent that could regulate growth and multiplication of tested bacterial species.
