Anti-Helicobacter pylori activity of mushrooms



Inhibitory effects of the mushrooms on the growth and urease of Helicobacter pylori (HP), which is associated with human gastroduodenal diseases such as gastritis, peptic ulcer and gastric carcinoma, were investigated. Most of the mushroom extracts did not show inhibitory effect on HP urease except Coriolus versicolar, Auricularia auricula, Sarcodon aspratus and Flammulina velutipes. The extract of Ganoderma lucidum, Coriolus versicolar, Gyropora esculenta and Agaricus bisporus var. albidus inhibited the growth of HP. When their extracts were fractionated, the ether fraction of Ganoderma lucidum and Agaricus bisporus var. albidus were the most effective. Among seven components seperated from the ether fraction of G. lucidum extract by silica gel column chromatography, P3 was the most potent: MIC was 200 μg/ml. However, P3 did not inhibit the urease.
