摘要
以单因素试验为基础,通过L9（3^4）正交试验研究超声波功率、超声波温度、提取次数对红景天苷提取率的影响。结果表明,超声波功率、超声波温度、提取次数对红景天苷提取率均有不同程度的影响,其中超声温度的影响显著。L9（3^4）正交试验优化后的提取适宜方案为：超声波功率500 W,超声波温度40℃,在此条件下提取4次。在最佳条件下,红景天苷提取率可达2.343%。
The effect of power of ultrasonic wave, temperature, and times on extraction rate of salidroside was studied through single-factor experiment and L^9（3^4） orthogonal experiment, results showed that power of ultra-sonic wave, temperature, and times had different impacts, orthogonal experiment analysis showed that temperature appreciably impacted.The optimum conditions for salidroside extraction were： power of ultrasonic wave 500 W, treating at 40℃, under these conditions extracting for 4 times.Under the optimal circumstances, the extraction rate of salidroside could be up to 2.343%.
