Pakistan journal of pharmaceutical sciences, 2020

Abstract

Five medicinal plants Mentha piperita L., Trachyspermum ammi L., Viola odorata Linn., Matricaria chamomilla L. and Foeniculum vulgare Mill. were selected for their in vitro and in vivo evaluation of anti-Helicobacter pylori activity. In vitro evaluation was performed by using disk diffusion method and minimum inhibitory concentrations were noted while rat models were selected for in vivo activity against four Helicobacter pylori strains isolated form gastric mucosa. Mentha piperita showed largest zone of inhibition with 9 mm diameter among all other extracts. All the plants showed promising anti-Helicobacter pylori activity against four isolates and a reference strain at concentrations of 125, 250, 500 and 1000 μg/ml in comparison with Amoxicillin 1 μg/ml but least MIC was exhibited by Mentha piperita followed by in vivo testing where it competed Amoxicillin at 1000 mg/kg by achieving 80% eradication of Helicobacter pylori in mucosa of infected rats justified by histological examina...
