Based on their biological activity, phenols from rosemary extract were evaluated for inhibition of Helicobacter pylori. Contents of total phenolic compounds and inhibition zone of water and ethanol extracts from rosemary were 24.3 mg/g and 25.7 mg/g, and 11 mm, 14 mm, and, at 200 μg/mL phenol content, 20.9% and 78.2% inhibitory activities were observed, respectively. Electron donating abilities and 2.2-Azino-bis-3-ethylbenxothiazoline-6-sulfonic acid cation radicals of water and ethanol extracts were 89.1% and 62.0% and 98.4% and 96.5%, respectively. Thiobarbituric acid reactive substances values of all extracts were lower than that of control.
