Abstract
1. Process for preparing mucopolysaccharides or MPS possessing high antithrombotic activity, characterized by the fact that compositions formed form a majority of MPS chains having a molecular weight of about 1800 to 8000 daltons, a YW titer and a ratio of the YW/USP titers higher than those of heparin to at least one fractionation step, in order to selectively separate from said compositions at least the major part of chains having MW lower than about 2000 and those having a higher MW but a sulfate content lower than the sulfate average contents of the mixture chain and that the fractions devoid from said chains are recovered, said fractions having a lower ratio of YW/USP titers than the starting compositions but higher than the one of heparin with USP titer higher than the one of the starting compositions.
