摘要
从万寿菊花中萃取叶黄素酯是制备叶黄素过程中的重要技术。本项研究对叶黄素酯的超临界CO2萃取进行了初步探索。实验结果表明,提高萃取压力、减小样品颗粒粒径以及减小萃取介质的极性均可增加叶黄素酯的萃取率。今后如果能在破坏叶黄素酯与花瓣组织介质的关联程度和降低萃取介质极性两个方面取得进展,超临界流体萃取有可能成为一种可应用于叶黄素酯萃取的技术。
This study is a preliminary investigation into the extraction of lutein esters by supercritical CO2. Results suggested that an increased pressure, reduced sample particle size and polarity of extraction medium resulted in an increased extraction yield. If progresses can be made in liberating lutein esters out from the flower tissues and the polarity reduction of extraction fluid, supercritical fluid extraction （SFE） can be a promising extraction technique for lutein ester extraction.
