To provide a hyaluronidase activity inhibitor containing as a component a safe and easily ingestable bamboo extract composition using the skin of Phyllostachys pubescens of a natural product as a raw material, to provide an antibacterial agent against Helicobacter pylori, and to provide a safe and easily ingestable bamboo extract composition using the skin of the Phyllostachys pubescens of the natural product.
The hyaluronidase activity inhibitor contains the bamboo extract composition obtained by adding an organic solvent or the organic solvent and water to a treated material obtained by treating the bamboo skin by a hydrolysis method to carry out the extraction as an active ingredient. The inhibitor can inhibit the development of allergy affected by the hyaluronidase activity and gastritis or the like caused by the Helicobacter pylori, because the bamboo extract composition has the hyaluronidase activity-inhibiting activity and the germicidal activity effective to the Helicobacter pylori.
