benzofuran trimers,  as well as polymeric lignins. A new sulfated β-O4 lignin (SbO4L) has been discovered which has shown a dual mechanism of action for anti-thrombosis.
The discovery of a new sulfated β-O4 lignin (SbO4L) with dual mechanisms for preventing blood clots is significant in the field of anti-thrombosis research.  It involves benzofuran trimers and polymeric lignins.
