STUDY ON EXTRACTION TECHNOLOGY OF YELLOW PIGMENT FROM CARTHAMUS TINCTORIUS WITH MICROWAVE EXTRACTION

Chuntao Kuang

Abstract

The extraction technology of yellow pigment from Carthamine were studied in this paper.Regarding hydroxy safflor yellow A as the standard,the conditions of microwave extracting yellow pigment were discussed by using the MAS-I microwave extraction system,including microwave extraction temperature,extraction time and the volume of extraction solvent.According to the results of single fraction experiments,the optimized conditions of microwave extracting yellow pigment were obtained by orthogonal experiments : extraction temperature was 70 ℃;extraction time was 20 min;ratio of material and solvent was 100 mL/g;extraction times was 3.
