antimicrobial properties and promoting healing of wounds. As a kind of polysaccharides in Bletilla striata
a traditional Chinese medicine
Bletilla striata polysaccharide has the function of hemostasis
detumescence and can promote the granulation. In this study
alginate and Bletilla striata polysaccharide were used as raw material
and the composite hemostatic powder was prepared by using lyophilization method. The water absorption rate was measured
and the hemostatic performance was evaluated by using in vitro blood coagulation test and the bleeding animal model. The results indicated that when the amount of porogen in calcium alginate porous microspheres was 0.5%
and the mass ratio of calcium alginate porous microspheres with Bletilla striata polysaccharide was 1∶1
the composite powder showed the best hemostatic effect.
