Propolis possesses antimicrobial, anti-inflammatory, anaesthetic and immunostimulating activities. The aim of this study was to evaluated chemical composition and in vitro anti-Helicobacter pylori activity of eight propolis ethanolic extracts form different region in Korea. The chemical composition of eight Korean propolis was investicated by absorption spectrophotomety and UHPLC. Total penolic and total flavonoids content ranged between 21±1.5 and 31±1.8 gallic acid g/100 g and 7.2±0.9 and 24.4±1.9 quercetin g/100 g, respectively. The p-coumaric acid as standard components content ranged between 0.29±0.00 and 2.34±0.02 mg/g using UHPLC. Cinnamic acid content between 0.43±0.00 and 1.33±0.01 mg/g. 80% ethanolic extract of propolis against H. pylori was evaluated by using the disc diffusion method. Ethanol was used as a control. Mean diameters of H. pylori growth inhibition using 10 μg/mL, 50 μg/mL or 100 μg/mL ethanol propolis per disc were 0, ranging from 0.9 to 2.1 mm and from 1.9 to 3.5 mm, respectively. In conclusion, variation in the chemical composition of Korean propolis were mainly due to the difference in the preferred regional plants visited by honeybees. Also Korean propolis possesses considerable antibacterial activity against H. pylori. There was not confirmed a correlation between the chemical composion contens and anti-H. pylori effect. The potential of propolis in the prevention or treatment of H. pylori infection is worth further extensive evaluation
