Antimicrobial effectiveness of Vitex negundo leaf extracts

摘要

Methanol and water extracts of the leaves obtained from Vitex negundo plant have been applied on to the textile materials and its antimicrobial effectiveness is assessed against Gram negative and Gram positive bacteria. Extracts of Vitex negundo leaves show antimicrobial efficacy even after multiple washes of the samples and, against perspirations of both acidic and alkaline pH values without any significant increase in the fabric stiffness. Samples treated by exhaustion method exhibit the bactericidal effect while microcapsules treated samples exhibit the bacteriostat effect. The extracts of leaves can potentially be used for controlling the proliferation of microbes and for finishing of fabrics for antimicrobial effectiveness.
