  • Sulphated polysaccharides, anticoagulant agent and anticomplementary agent obtained from brown algae fucuses and method of obtaining same
    Patent number: 5321133
    Abstract: The invention relates to sulphated polysaccharides obtained from fucuses extracted from pheophyceae. The molecular weight of these polysaccharides is greater than 5 and less than 40 Kda; their sulphur content is greater than that of the original fucus and they contain less than 0.15% of contaminant proteins. Applications as anticoagulant and anticomplementary agents.
