【摘要】 [目的]对红花黄色素提取条件进行了系统研究。[方法]以羟基红花黄色素A为对照品,对萃取红花黄色素影响因素,包括提取剂,提取温度、提取时间、提取溶剂体积等进行单因素的考察。[结果]在单因素试验基础上,选定蒸馏水为最佳提取剂。通过正交试验最终确定了红花黄色素的适宜提取条件为:提取温度60℃,提取时间50 min,液固比为100(ml/g),提取次数为4次。[结论]该研究确定了红花黄色素的适宜提取条件,为生产工艺参数的选择提供了依据。更多还原

【Abstract】 [Objective] The extraction technology of yellow pigment from Carthamine(Carthamus tinctorius) were studied.[Method] With hydroxy safflor yellow A as the standard,the conditions of extracting yellow pigment were discussed,including extraction solvent,extraction temperature,extraction time and the volume of extraction solvent.[Result] Water was chosen as the extracting agent by comparison of the extracting effects of the several dissolvents.The preferential extracting conditions were obtained by orthogonal experiments: Extraction temperature was 60 ℃,extraction time was 50 minutes,ratio of material and solvent was 100(ml/g),extraction times was 4.[Conclusion] The study confirmed the suitable extraction conditions of yellow pigment from Carthamus tinctorius,and provided the basis for choosing production technology parameters.更多还原
