- 摘要:
- 以新鲜库拉索芦荟为试材,采用改良的超声醇沉法提取芦荟多糖,并用旋光法测定了多糖在不同浓度HCl条件下水解反应动力学。结果表明:水解反应很好的符合一级动力学方程;改良的超声醇沉法简化了多糖提取工艺,耗能少,产率高,适用于实际生产;特别是用简单的旋光法测定的芦荟多糖的可控酸水解,为制备目标分子量规格的活性低聚糖奠定了理论基础。
- Abstract:
- Taking fresh Curacao aloe as material,polysaccharide was extracted by the optimized ultrasound alcohol sedimentation method,the polysaccharides was determinated in different concentration of HCl conditions with the optical method.The results showed that the hydrolysis reactions was coincidence with first grade equation.The optimized traditional alcohol sedimentation method was suitable for the industrial production because of simplified procedure and low energy consumption;these results would lay a theoretical foundation for the development application of aloe polysaccharide,especially in the preparation of active oligosaccharide with certain molecular under the acid-controllable conditions.
