Abstract: Laver was broken by ultrasonication at 800W for 800s and extracted with deioned-water at 30 volumes. The crude phycobiliprotein including phycoerythrim and phycocyanin was purified by precipitating with ammonium sulphate of 45% and dialyzing. The two active fraction were received by hydroxylapatite(HA) column chromatography. The purities of phycobiliprotein was up to 4.32. The phycoerythrim and phycocyanin exhibited maximum absorbtion at 558nm and 616nm respectively.

Key words: laver, phycobiliprotein, extraction, purification
