摘　　要：以北虫草为原料,优化用超声波法同步提取北虫草中虫草素和虫草多糖的工艺。基于单因素试验结果,利用响应面法考察超声时间、超声温度、液固比对虫草素含量和虫草多糖得率的影响。结果表明:虫最佳提取工艺条件为液固比40∶1(mL/g)、超声温度55℃、超声时间50 min。在此条件下,北虫草中虫草多糖得率为75.3%,虫草素含量为2640.8 mg/kg。Cordyceps militaris was used as raw material to optimize the ultrasonic simultaneous extraction process of cordycepin and cordyceps polysaccharide from Cordyceps militaris.Based on the single factor experiment results,response surface methodology was used to investigate the effects of ultrasonic time,ultrasonic temperature and liquid-solid ratio on the cordycepin content and cordyceps polysaccharide yield.The results showed that the optimum extraction conditions were liquid-solid ratio of 40∶1(mL/g),ultrasonic temperature of 55℃ and ultrasonic time of 55 min.Under the conditions,the polysaccharide yield was 75.3%,and the cordycepin content was 2640.8 mg/kg.
