ABSTRACT
Objective To optimize the sulfation-conditions of Bletilla striata polysaccharide (BSPS). Methods BSPS was sulfated with chlorsulfonic acid-pyridine. Reagent proportion, reaction temperature, and reaction time were selected with substitution degree and yield as index by L_9(3~4) orthogonal design. Results Results showed that the condition with 6∶1 volume ratio of pyridine and chlorine sulfonic acid, reaction temperature of 85 ℃, reaction time of 2 h was the optimum. Conclusion The optimal method for sulfation of BSPS is feasible, and it provides valuable parameters for further enlarged test.
