CA 2484736

It is intended to provide a safe and highly efficacious antibacterial composition which is to be used in products mainly taken into the human or animal body or employed in the oral cavity such as foods and oral hygienic preparations without damaging the tastes of foods and drinks. The above composition contains gallocatechin gallate as a potentiator for antibacterial catechins. In particular, the antibacterial effects of the antibacterial catechins on bacteria causative of human decay such as Streptococcus mutans are enhanced thereby. The composition can be produced by mixing antibacterial catechins with gallocatechin gallate. Alternatively, it can be produced as a composition containing as the main component an adsorption fraction which is obtained by subjecting a solvent extract of tea leaves to adsorption by a synthetic adsorbent selected from among aromatic synthetic adsorbents and methacrylic synthetic adsorbents.

L'invention concerne une composition antibactérienne sûre et hautement efficace destinée à être utilisée principalement dans des produits absorbées par l'organisme humain ou animal, ou utilisés dans la cavité buccale, tels qu'aliments ou préparations pour l'hygiène buccale, sans porter atteinte au goût des aliments et des boissons. Ces compositions contiennent du gallocatéchine gallate utilisé comme agent de potentialisation des catéchines antibactériennes. Cette composition permet de renforcer en particulier les effets antibactériens des catéchines antibactériennes sur les bactéries responsables de la carie chez l'homme. On peut préparer ces compositions en mélangeant des catéchines antibactériennes avec du gallocatéchine gallate. Dans d'autres modes de préparation, cette composition contient en tant qu'ingrédient principal une fraction adsorbée qu'on obtient en soumettant un extrait soluble de feuilles de thé à une adsorption par un adsorbant synthétique choisi parmi les adsorbants synthétiques aromatiques et les adsorbants synthétiques méthacryliques.
