Antibacterial survey of different extracts of Peganum harmala L. different parts in North east of Golestan province (Inche Borun)
Abstract
Peganum harmala L. belongs to Zigophyllaceae family is one of the most important medicine plants with wild distribution in stepic and semi stepic of Golestan province. In this research, after phenology ethnopharmacological data obtained from turkman rural people. Different parts of plant were collected in May to late of September 2008 in dry stepic region of North east of Golestan province (Inche Borun). Aqueous, infusion and ethanolic extract were obtained by percolation method and their antibacterial effect was evaluated by disc diffusion and well methods. Inhibition zone after 24h incubation of 37 and their antibacterial activity were assessed by Pearson chi-square (P<0.05).
