摘要
以和田玉枣为主要研究对象,对超声波辅助提取和田玉枣cAMP的工艺进行系统研究,并与传统溶剂浸提法进行对比。实验结果,超声波辅助提取和田玉枣cAMP的最优工艺条件为:乙醇体积分数15%,提取温度35℃、提取时间50min、液料比20∶1、超声波功率400W;在此工艺条件下,和田玉枣cAMP平均提取率为771.95μg/g·dw。各因素影响和田玉枣cAMP提取率的影响程度依次如下:提取温度>液料比>提取时间>超声波功率。超声波辅助法与传统溶剂浸提法相比,具有提取速度快,提取率高,提取温度低等明显优势。
The ultrasonic extraction of cAMP from Hetianyuzao systemically was studied,and that was compared with the traditional solvent extraction, Results were as follows-the technology of extracing cAMP from Hetian jade jujube with ultrasonic extraction was that.ethanol concentration 15% ,ultrasonic extraction temperature 35℃, ultrasonic extraction time 50rain,solid/liquid ratio 20:1 ,ultrasonic power 400W. Under the optimal extraction conditions,the average yield of cAMP was 771.95μg/g .dw. The effect sequence of four main factors for the yield were as follows :ultrasonic extraction temperature〉liquid/solid ratio〉ultrasonic extraction time 〉ultrasonic power. Compared with traditional solvent extraction, ultrasonic extraction had obvious advantages including the faster extraction speed, higher yield rate and lower temperature.
