Helicobacter pylori are well acknowledged as a major cause of gastrointestinal ailments and gastric cancers. Therefore, the present study aimed to investigate the potential in vitro activity of Desmostachya bipinnata against H. pylori, focusing on the determination of the most active extract responsible for the anti-helicobacter activity to produce new active drug from natural source. Desmostachya bipinnata total alcohol and successive extracts were in vitro tested against H. pylori. All extracts showed promising anti Helicobacter pylori activities. The most effective extract was diethyl ether extract, it showed 75% growth inhibition of the clinical Isolates bacterial Helicobacter pylori, in addition it showed high count reduction on the selected organisms in the different concentrations used (2xMIC, MIC & ½ MIC) compared with the untreated controls as well as the other extracts (chloroform, ethyl acetate and n-butanol). The oral median lethal dose (LD50) of the alcohol extract of the plant by doses up to 5000 mg/kg didn’t showed any mortality or morbidity, in addition no side effects were recorded on both liver and kidney functions this means that the extract was safe for use.
