摘要
研究了利用正己烷和乙醇混合溶剂,或石油醚溶剂,从万寿菊花粉提取、分离、提纯叶黄素的方法。最适工艺参数:正己烷(为提取剂)和95%乙醇(体积比3∶2),提取温度60℃,提取时间4~5h,提取次数5~6次,液料比15∶1(mL∶g);皂化温度55~60℃,皂化时间6h。按本工艺条件操作,万寿菊花中叶黄素得率为7.5%~7.9%。
Method of extraction, separation and purification of lutein from marigold ( Tagetes erecta Linn. ) flowers by hexaneethanol, or petroleum ether were investigated. The optimum processing conditions are: hexane (as extraction solvent) and 95 % ethanol (volume ratio 3:2), extraction temperature 60℃, extraction time 4-5 h, extraction times 5-6 times, ratio of extraction solvent to marigold 15:1 (mL: g), lutein yield 7.5 %-7.9 % of dry marigold flowers
