摘要
通过单因素和L16(45)正交实验对金鸡菊花中黄色素的提取工艺进行了研究,获得提取最佳工艺条件为:pH值为3、体积分数65%的乙醇为浸提剂,按料液比1∶12投料,在50℃下浸提5h.
The extraction technology of yellow pigments in Coreopsis basalis was studied by use of single factor test and L16（4^5） orthogonal experiment design method in this paper. The experimental results indicated that the optimum conditions were the extraction reagent 65 % alcohol with pH 3, twelve times of volume of extraction reagent as large as the weight of Coreopsis basalis and extraction temperature at 50℃ for 5 hours.
