Abstract
Traditionally, plants and their products are used as a folk medicine for the treatment of curable and incurable diseases for a long time in many areas of the world. However, there is a lack of systematic study of the antibacterial activity of Suaeda maritima (S. maritima). The present study is to estimate the antibacterial activity of various extracts of newly discovered species S. maritima plant which is collected from Oman. The methanol extract was prepared by the Soxhlet method and it was fractionation by different solvents to give different crude extracts. The antibacterial activity was assessed by using the agar disc diffusion method in which the extracts at different concentrations were applied to the disc by putting them in sterile filter paper of about 6 mm. The agar discs were incubated for 24 h and measure the inhibition zone of antibacterial activity. The range of the inhibition zone was between 7 and 12 mm. Overall all concentrations of each extract of S. maritima showed inhibition activity against the applied bacterial strains. The results found that the hexane extract at all concentrations was possessed the highest activity against the used two Gram-positive and two Gram-negative bacteria strains. In conclusion, the highest antibacterial activity hexane extract from the S. maritima could be used for the treatment of infectious diseases. In addition, the observed antibacterial activity of the selected plant could be due to the presence of high contents various group bioactive compounds.
