| 摘 要： | 采用温浸法研究不同粉碎粒度对黄芪多糖提取率的影响,实验结果表明:粉碎粒度80目时粗多糖提取率为16.29%,粗多糖纯度为61.67%;45目时提取率为9.90%,粗多糖纯度为53.33%;30目时提取率为5.76%,粗多糖纯度为48.40%,多糖提取率和粗多糖的纯度随着粉碎粒度的减小显著增大,这些数据为黄芪多糖开发提供了重要依据。

| Abstract: | The research aims to study the influence to extraction rate of astragalus polysaccharide at differ‐ent grinding particle size by Ultrasonic treatment. The results of the experiment show that the polysaccha‐ride extraction rate is 16. 29% and the purity is 61. 67% when the grinding particle size is 80 mesh. The polysaccharide extraction rate is 9. 90% and the purity is 53. 33% when the grinding particle size is 45 mesh. The polysaccharide extraction rate is 5. 76% and the purity is 48. 40% when the grinding particle size is 30 mesh. The extraction rate of astragalus polysaccharide and the purity are in significant increase with the decrease of grinding particle size. These data are the important basis for the development of astragalus polysaccharide. |
