摘要: 本文对新疆紫草进行了超临界萃取工艺研究并与有机溶剂萃取的结果进行比较。结果表明:超临界萃取在32℃、压力27MPa下重量得率最高,达4.2%;紫草素衍生物也达最高,为3.59%。超临界萃取比有机溶剂萃取能得到更多紫草萘醌组分。超临界萃取的紫草色素含杂质更少。

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
