摘要
用氨基磺酸法对党参多糖进行硫酸化修饰,采用均匀设计U8(43)对党参多糖硫酸酯化工艺进行优化设计,并用氯化钡-明胶法测定硫酸根的取代度。确定了党参多糖硫酸酯化最佳工艺条件:温度为60℃、时间15min、投料比为1:0.04(g/mol)。此种方法能够为多糖硫酸化的进一步研究提供研究参数。
Codonopsis pilosula polysaccharide (CPPS) was modified by sulfamic acid. Uniform-design method U8(4^3) was used, taking substitution degee and productivity as index. It showed that the reaction temperature of 60 %, reaction time of 15 min and condition with 0.04 mol. It provides valuable parameters for further studies on structure-activity ralationship of CPPS and S-CPPS.
