Study on ultrasonic technology of polysaccharide from Ficus hirta Vahl
-
摘要: 目的: 探讨采用超声提取法从五指毛桃中提取多糖的工艺条件,为多糖的超声提取提供理论依据。 方法: 用硫酸-苯酚法测定多糖含量,采用正交试验法研究多糖的提取工艺。 结果: 最佳工艺为药材粉碎过60目筛,加12倍量水,超声40 min。 结论: 超声提取法可用于五指毛桃多糖的提取。Abstract: Objective: To discuss the technoloqy and qualification of the ultrasonic extracting method of polysaccharide from Ficus hirta Vahl,to provide theories for the super voice of polysaccharide. Methods: Polysaccharides were extraeted with orthogonal experi- ment by ultrasonic method,and the content was determined by spectrophotometry. Results: The optimum technology was to extract by ultrasonic wave for 40 mins,adding 12 folds of water,and crushed to 60 eyes. Conclusion:: This method is easy to operate and extract and able to obtain a high content of polysaceharide.
