丹参多糖提取工艺研究

Extraction of Polysaccharide in Root of Salvia miltiorrhiza

摘要: 以丹参为原料，水为提取剂，采用微波辅助法提取丹参多糖。通过控制单因素作用时间、功率、温度、液料比，再结合正交实验对提取丹参多糖的工艺条件进行优选，从而得出采用微波辅助法提取丹参的最佳工艺：超声功率350 W、微波时间120 s，超声温度80℃、液料比25:1，此时丹参多糖提取率可达84.556 mg/g。

Abstract: The polysaccharide in root of Salvia miltiorrhiza was extracted with water with the aid of microwave. Through single factor experiment and orthogonal experiment, the optimal process parameters were obtained: microwave time 120 s, ratio of liquid to material 25:1, microwave power 350 W, microwave temperature 80˚C. Under the optimal conditions, the extraction rate was 84.556 mg/g.
