Abstract
Sulfated derivatives of xylan (isolated from Bétula pubéscens wood) with average molecular weight ~34 kDa, sulfur content of 11.3-17.5%, a degree of substitution of 0.74-1.64 are anticoagulants of direct type of action. Antithrombin and antifactor Xa activities in three tested xylan samples did not differ and reached 30.8-31.8 and 13.5-14.3 U/mg, respectively.
Keywords:
anticoagulant; antithrombin activity; sulfatation; xylan.
