【摘要】 目的研究桃仁多糖提取工艺参数。方法通过单因素实验及正交实验研究固液比、温度、时间及提取次数对桃仁多糖提取率的影响,用苯酚-硫酸法测定其多糖含量。结果桃仁多糖提取最佳工艺条件为提取温度80℃,提取时间4h,固液比1∶30,提取2次。结论该方法简单、环保,提取效果好,桃仁中多糖含量为1.83%。更多还原

【Abstract】 Objective The extraction for polysaccharides in Semen Pruni Persicae with water was studied and the content of polysaccharide was determined.Methods The effects of ratio of material to water,extracting temperature,extracting time and extracting times on the yield of the polysaccharides were studied through both single factor and orthogonal experiments.The method of phenol-sulfuric acid was employed to determine the content of the polysaccharides.Results The optimum technological parameters were as follows: extracting temperature 80℃,extracting time 4 h,the ratio of material to water 1∶30,and extraction for 2 times.Conclusion The extracting method studied in this paper is simple,environmental protective and efficient.The extracting yield of polysaccharides in Semen Pruni Persicae is 1.83%.更多还原
