Study on Extraction Technology of Brassica Campestris Pigment

The brassica campestris was used as raw material,the extraction and purification craft of the brassica campestris pigment were studied,and some theoretics base and experiment data were provided for the application of the brassica campestris pigment.The results showed that the optimum technique of extracting water condition was:the ratio of liquid weight to solid weight 1:5 for 3.0 h at 90 ℃,the yield of the extracted pigment 2.6%.The optimum microwave extraction craft were:microwave time 5 min,microwave firepower,middle-high fire,the ratio of liquid weight to solid weight 1:5,the yield of the extracted pigment 1.2%.
