It is disclosed a method for determining the biological activity of defibrotide, which comprises the steps of: a) bringing into contact defibrotide, mammalian euglobulin and a substrate specific for the plasmin which, by reaction with the plasmin, provides a measurable product; and b) measuring the amount of product formed at successive times, to thereby determine the biological activity of the defibrotide. Liquid defibrotide formulations are also disclosed, preferably water solutions, having a defined biological activity and, in particular, having an activity of 25 to 35 IU/mg of defibrotide, preferably from 27 to 32 IU/mg and, more preferably, from 28 to 32 IU/mg.
