摘　　要：通过单因素试验和正交试验确定超声辅助有机溶剂法提取青花椒色素的最优工艺为:以无水乙醇为提取溶剂,花椒粒度为过100目筛,超声提取时间为30 min,提取功率为120 W,料液比为1∶50(g/mL),此条件下青花椒色素的吸光度最大,为0.4383,说明青花椒色素的提取率达到最高。与传统的有机溶剂浸提法提取青花椒色素相比,超声辅助有机溶剂法中青花椒色素提取率有明显提高。Through single factor experiment and orthogonal experiment,the optimum extraction process of Zanthoxylum schinifolium pigments by ultrasonic-assisted organic solvent method is determined as follows:absolute ethanol is as the extraction solvent,particle size of Zanthoxylum schinifolium is 100 mesh,ultrasonic extraction time is 30 min,extraction power is 120 W,solid-liquid ratio is 1∶50(g/mL).Under such conditions,the absorbance of Zanthoxylum schinifolium pigments is the highest of is 0.4383,indicating that the extraction rate of Zanthoxylum schinifolium pigments reaches the highest.Compared with the traditional organic solvent extraction method,the extraction rate of Zanthoxylum schinifolium pigments by ultrasonic-assisted organic solvent method is significantly improved.
