摘要
运用超声波技术提取杜仲叶 ,具有防止提取物在长时间高温下氧化褐变 ,并有省时、节能、提取率高等优点 ,其最佳提取工艺参数为 13～ 2 6kHz ,低频超声处理45min ,温度 5 0℃左右。另外 。
Extraction of Eucommia ulmoides leaves assisted by ultrasonic wave has the advantages to prevent oxidation and browning of the extractives under high temperature at shorter time with less energy consumption to obtain high extraction efficiency.The optimum technological parameters are:13～26 kHz low frequency ultrasonic wave treatment for 45 min at approximately 50 ℃.Mechanism of ultrasonic wave extraction was also discussed.
