摘　　要：研究了从万寿菊干花颗粒中分离皂化叶黄素的生产工艺。得到最佳的生产工艺条件:提取溶剂采用石油醚,提取温度为50℃,提取时间为每次5h,提取2次,料液比(g∶mL)1∶7;皂化时NaOH的浓度为35%,皂化温度60℃,皂化时间6 h;经皂化后处理,游离叶黄素的纯度达到98.6%。The extraction and saponification of lutein from marigold dried flower grains were investigated. The optimum process conditions were selected as follows： petroleum ether was chosen as extraction solvent, extraction temperature was set at 60%, extraction process lasted for 6 h, 2 times extraction, and the ratio of marigold to extraction solvent was 1：7 （g：mL）. The results showed that the optimal saponification parameter was： 35% NaOH, at 60℃ for 6h. After the saponification and purification, the purity of free lutein reached to 98.6% .
