The Activity of Aquatic Extract of Ziziphus Spina-christi against Bacteria, an in Vitro Study

Background: Medicinal plants such as Ziziphus spina-christi, was described as one plant in which one of its parts contain compounds that used for chemotherapeutic purposes or medical crude for the synthesis of useful drug. So this useing of plants in treating ailments has been in practice since long time ago. Aims: The present paper aimed to evaluate the antibacterial activity of (leaves, stem bark and the combination of leaves + stem bark) aqueous extracts of Z. spina–Christi .in vitro. Methods: Antibacterial effects of( aquatic leaves, aquatic stem park and combination of leaves + stem bark) extracts against five Gram-positive and eight Gram-negative bacteria- including Staphylococcus aurus, Staphylcoccus epidrmidis, Streptococus pyognes, Staphylcocus saprphyticus, Streptococus pnemniae, Pseudomnas aeruginsa, Enterbacter sp, Klebiella pneuoniae, Eschricha coli, Salmonlla typehi, Protus mirabilis, Seratia marcecans, Acinetbacter. Results: Antibacterial actity of these extrats by well-diffusion method were measured by inhibition zones of five Gram-positive, eight Gram-negative pathognic microbes. All organisms of this study were highly sensitive to comination of leaves + stem bark extract, then stem bark aqueous extract, finally all tested organisms were slight sensitivity to leaves aqueous extract. Conclusion: Sidir aquatic extracts (leaves, stem bark and combination of leaves + stem bark) had an inhibitory effect against all tested bacterial species. This plant also need further work to discover new broad spectrum bioactive compounds.
