以风干的樟树叶为原料,用双水相体系提取樟树叶多酚,采用二次回归正交旋转法研究5个影响因素（超声波功率、液料比、提取温度、浸提时间、超声波时间）对提取率的影响,并建立回归数学模型对试验结果进行分析。结果表明,樟树叶多酚最佳的提取工艺参数是超声功率为255 W,料液比为1∶39（m∶V）,浸提时间为96 min,浸提温度20.9℃。该条件下,樟树叶多酚得率达到3.3%。

Aqueous two-phase extraction（ATPE）,a new extracting technology,has been paid more and more attention.In order to optimize the extraction technology of camphotree-polyphenol,effects of ultrasonic power,ratio of material to solvent,extracting time,extracting temperature and ultrasonic time on extraction efficiency were studied.Taking air-dried camphotree leaves as raw material and ATPE as the extracting method,and then the regression model was established by using quadratic regression rotational combinational design.The optimum conditions for t...
