为博落回提取血根碱开发新原料,为工业化生产提供依据.在单因素试验的基础上,以血根碱转移率为评价指标,分别对博落回茎叶使用酸性乙醇回流和酸水渗漉法进行工艺研究.试验结果表明酸性乙醇回流提取工艺最佳条件为乙醇体积分数90%,液固比30:1 ml/g,硫酸浓度0.12%,提取温度80 ℃,提取时间2 h,血根碱转移率达到(89.36±0.49)%(n=5, R2=0.54%),最终得到博落回茎叶提取物收率(24.27±0.92)%(n=5,R2=3.77%),血根碱含量(1.65±0.06)%(n=5,R2=3.36%);酸水渗漉提取工艺最佳条件为硫酸浓度1%,浸泡时间30 min,渗漉温度80 ℃,溶剂用量30倍,渗漉速度0.5 ml/min,血根碱转移率达到(83.63 ± 2.09)% (n=5,R2=2.4...

For developing new materials and of?fer a sound evidence for the mass production in?dustry, the extraction process of sanguinarine from the stem and leaf of Macleaya cordata was studied in this work. On the basis of single fac?tor experiment, the factors affecting the transfer rate of sanguinarine investigated by ethanol re? flux extraction and percolation extraction. The experiment results indicated that the optimum condi?tions for the ethanol reflux extraction were obtained as follows:the ethanol concentration was 90%, liq?uid-solid ratio was...
