摘要
利用有机溶剂浸提枸杞子中的色素,通过单因素和正交实验确定了提取枸杞色素的工艺条件为:用石油醚-丙酮(体积比为4∶1)混合溶剂浸提,液料比为3mL∶1g,在50℃浸提1.5h,反复4次,浸提率可达91.6%。
The paper studied the optimum technology condition of extracting pigment using organic solvent from fructus lycii with single factor experiments and orthogonal tests. The result showed that the optimum extraction condition was 3:1(ml/g)-50℃-1.5 hour/time-4 times with petroleum ether-acetone(4:1 V:V).Under these conditions-the extraction rate was91.6%.
