Total phenolic contents and inhibition zone of rosemary extracts were estimated to be 25.7 mg/g and 14 mm at 200 µg/mL of phenolic contents, respectively. The Sephadex

All isolated compounds were tested for antimicrobial activity against H. pyori. The purified single compound showed less antimicrobial activity against H. pylori than the mixed purified compounds, which generate A+B, A+E, C+D, C+E (each 200 µg/disc) excellent as large clear zone by synergy effect. These results indicate rosemary extracts are preventive agents against H. pyori.
