摘　　要：建立了一套超临界CO2流体萃取实验装置，对光菇子的秋水仙碱（colchine）成分进行了超临界CO2流体萃取研究，并用HPLC法作了含量测定。结果表明，加夹带剂的超临界CO2流体萃取法的提取率约提高为传统溶剂萃取法的1．25倍。An experimental set-up has been established for supercritical CO2 fluid extraction. A study on supercritical CO2 fluid extraction of colchicine from Guangguzi (Iphigenia indica ) was carried out. The assay of colchicine was performed by HPLC. Results showed that the extraction rate of supercritical CO2 fluid extraction with entrainer was about 1. 25 times as that of traditional solvent extraction.
