Abstract: Supercritical CO2 extracted euchroma(Royle) Johnst was investigated and compared with organic solvent extraction.The resulted showed that the yield is up to 4.2% at 32℃ 27MPa by SFE and the yield of Naphthaquinonic compounds is up to3.59% at the same conditions. More components is extracted at SFE than that at organic solvent extraction, and red pigmentcontains less non-Naphthaquinonic compounds at SFE than that at organic solvents extraction.

Key words: euchroma(Royle) Johnst, supercritical CO2 extraction, euchroma(Royle) Johns pigments
