Abstract: In this paper, the recent researches for phycobiliproteins on extraction and purification were introduced in the aspects of extraction of some raw materials, crushing cell methods, crude extraction methods and purification methods. The usual extracting materials were concluded as Spirulina, Polysiphonia urceolasa, Por-phyra yezoensis etc. There were 5 ways to cruch cell such as repeated freezing and thawing method and chemical reagent method. And there had 4 crude extraction methods such as the salting - out method to extract the crude phycobiliproteins. Hydroxylapatite column chromatography, DEAE - celluose column chromatography and Gel column chromatography were the usual purification methods. To get better results in the practice, diversified methods were often used.

Key words: Phycobiliproteins , Extraction , Purification
