摘要
对苎麻根中绿原酸的提取工艺进行了研究。以绿原酸提取率为考察指标,通过单因素实验和正交实验对提取条件进行了优化。确定了苎麻根中绿原酸的最佳提取条件为:乙醇体积分数50%、料液比1∶13(g∶mL)、提取温度90℃、提取溶液pH值5、提取时间100min,在此条件下,绿原酸的提取率为0.2759%。
The extraction process of chlorogenic acid from ramie root was studied.Using extraction rate of chlorogenic acid as evaluation index,the extraction conditions were optimized by single factor experiment and orthogonal experiment.Results showed that,the optimum extraction conditions of chlorogenic acid from ramie root were as follows：ethanol volume fraction was 50%,solid-liquid ratio was 1∶13（g∶mL）,extraction temperature was 90 ℃,pH value of extraction solution was 5,extraction time was 100 min.Under above conditions,extraction rate of chlorogenic acid was 0.2759%.
