Abstract

Aristolochia bracteata (Aristolochiaceae) is used in traditional medicines as a gastric stimulant and in the treatment of cancer, lung inflammation, and dysentery and snake bites. The present investigation was undertaken to evaluate the antibacterial activity of Aristolochia bracteata root extracts. Roots of A. bracteata were powdered and successively extracted with ethyl acetate, acetone, methanol, and water for 8 hours each using a Soxhlet extractor. Antibacterial activity of dried extracts was evaluated by the pour-plate method against a few Gram-positive and Gram-negative bacteria. All the crude extracts showed a broad spectrum of antibacterial activity. The ethyl acetate extract was found to be the most effective. This study shows the potential for replacement of synthetic preservatives by the use of natural extracts.
