Abstract: New techniques for extraction and analysis of natural pigments were introduced. New extraction techniques include supercritical fluid extraction, physical assistant extraction, molecular distillation and aqueous two-phase extraction. New analytical techniques are high performance liquid chromatography, high-speed countercurrent chromatography, high performance capillary electrophoresis and chromatography-mass spectrometry. Fundamental principles, characteristics and applications of new techniques were discussed, and the existing problems were pointed out. The applications and prospects of new techniques for extraction and analysis of natural pigments were explored.

Key words: natural pigments, extraction technique, analytical technique
