PAREKH, Jigna  and  CHANDA, Sumitra. In vitro antibacterial activity of the crude methanol extract of Woodfordia fruticosa Kurz. flower (Lythraceae). Braz. J. Microbiol. [online]. 2007, vol.38, n.2, pp. 204-207. ISSN 1517-8382.  http://dx.doi.org/10.1590/S1517-83822007000200004.

The antibacterial activity of the crude methanol extract of Woodfordia fruticosa Kurz. flower was evaluated at two different concentrations by the agar well diffusion method. The methanol extract of the flower exhibited antibacterial activity at varied levels except against Bacillus subtilis and Micrococcus flavus. The methanol extract was most active against Pseudomonas pseudoalcaligenes. The extract was more active against Gram-negative bacteria as compared to Gram-positive. The inhibitory effect of the extract was compared with standard antibiotics, amoxicillin and ciprofloxacin.

Keywords : Woodfordia fruticosa; antibacterial activity; crude methanol extract.
