ANTIBACTERIAL ACTIVITY OF METHANOLIC EXTRACTS FROM SOME SELECTED MEDICINAL PLANTS

Abstract

The present study describes antimicrobial activities of medicinal plants Jasminum grandiflorum L., Spinacia oleracea L., Coriandrum sativum L. and Zingiber officinale Roscoe. In the present investigation the antibacterial activity of the methanolic extracts of these plants were tested against twelve Gram-positive and eighteen Gram-negative bacteria at 1000 µg/disc concentration by disc diffusion method. The methanolic extracts of leaves of Jasminum grandiflorum and Spinacia oleracea showed significant antibacterial activity against some of the bacteria tested.
