Procedure for obtaining a cranberry extract, characterized in that from cranberry berries, genus Vaccinium macrocarpon and / or Vaccinium oxycoccus, a cranberry pulp extract containing a large percentage of type A proanthocyanidins is obtained, comprised between 1% and more than 20% with the vanillin-acid method and between 5% and more than 50% with the Bate S mith method, which has antibacterial, antiviral and non-stick properties: - by pressing the berry, - then, extraction of the proanthocyanidins contained in the pulp thus obtained with the aid of a hot aqueous solution or at room temperature, or of a hydroalcoholic solution at room temperature, operation which is followed by known solid-liquid separation techniques, - then, transfer over an adsorption resin of grafted silica type, which allows the anthocyanins and proanthocyanidins to be isolated from undesirable substances and - r recovery from the eluate of these same proanthocyanidins in the form of dry powder, by vacuum drying or lyophilization or atomization or nebulization.Procedimiento para la obtención de un extracto de arándanos, caracterizado porque a partir de las bayas de arándano, género Vaccinium macrocarpon y/o Vaccinium oxycoccus, se obtiene un extracto de pulpa de arándano que contiene un gran porcentaje de proantocianidinas de tipo A, comprendido entre 1% y más de 20% con el método de la vainillina-ácido y entre 5% y más del 50% con el método de Bate S mith, el cual presenta propiedades antibacterianas, antivirales y antiadhesivas: - por prensado de la baya, - después, extracción de las proantocianidinas contenidas en la pulpa así obtenida con ayuda de una solución acuosa en caliente o a la temperatura ambiente, o de una solución hidroalcohólica a temperatura ambiente, operación que va seguida de técnicas de separación sólido-líquido conocidas, - después, traspaso sobre una resina de adsorción de tipo sílices injertadas, la cual permite aislar las antocianinas y las proantocianidinas de las su
