Abstract
This study was designed to investigate the effect of medicinal herb extract on the antioxidant and antimicrobial activities against Helicobacter pylori, which is known as a ulcerogenic pathogen. The concentration of total phenolic compound of Scutellaria baicalensis(13.14%) was highest among water extracts and that of Ulmus parvifolia(15.12%) was highest among the ethanol extracts. The antioxidant activity of the water extract of Scutellaria baicalensis and of the ethanol extract of Ulmus parvifolia were 91.00% and 65.03%, respectively, in DPPH assay. The antioxidant activity of the water extract of Scutellaria baicalensis and of the ethanol extract of Ulmus parvifolia were 32.90% and 27.70%, respectively, in SOD assay. The antioxidant activity of the water extract of Ulmus parvifolia and of the ethanol extract of Glycyrrhiza uralensis Fischer was 2.15 and 2.17, respectively, in TBARS assay. In disc method, Scutellaria baicalensis showed the highest anti-microbial activity against H. pylori, followed by Glycyrrhiza uralensis Fischer among the water extracts and Glycyrrhiza uralensis Fischer showed the highest anti-microbial activity followed by Radix puerariae among ethanol extract.
