| 摘 要： | 本文研究了从万寿菊中提取叶黄素的强化工艺条件，对提取剂、皂化液浓度及皂化时间进行了考察．并确定出以二氯甲烷作提取剂、皂化液浓度为4％，皂化时澡为2h的适宜工艺条件．粗提物经柱层析分离，重结晶，再经过超临界流体沉淀处理后，可提高叶黄素的纯度．

| Abstract: | The technology of fitting conditions （the solvent, saponified concentration and saponification time） for extracting lutein from marigold is studied. The optimal conditions are as follows ： CH2Cl2-- the extracting solvent, saponified solution-- 4 % and saponification time- 2 hours. After column chromatographic separation, re-crystallization treatment and supercritical fluid precipitation treatment,the purity of lutein is improved. |
