超声辅助双水相体系提取水飞蓟中水飞蓟宾的工艺优选
Journal of Heilongjiang August First Land Reclamation University(2017)
Abstract
为优化水飞蓟中水飞蓟宾的提取工艺,以乙醇体积分数、硫酸铵用量、料液比和超声时间为自变量,水飞蓟宾含量为因变量,采用星点设计-响应面法优选超声辅助双水相体系提取工艺参数.研究结果表明,最佳工艺条件为:乙醇体积分数为57%,硫酸铵的用量为0.26 g·mL-1,料液比为25 mL·g-1,超声时间为19 min,水飞蓟宾含量为10.18 mg·g-1.该工艺适用于水飞蓟中水飞蓟宾的提取,方法简单,预测性较好.
