【摘要】 以厚朴酚含量和厚朴浸膏收率为指标,用正交试验法对中药厚朴的提取工艺进行了优选,实验选择乙醇浓度、乙醇用量、提取时间及次数四个因素,每个因素取三个水平。结果表明,乙醇浓度为65％,乙醇为药材量的8倍,热回流三次,每次120min,厚朴酚收得率高。更多还原

【Abstract】 To find out the optimal extraction process for magnoliae cortex, the extraction process was studied by orthogonal design with yield of the extracta sicca from magnoliae cortex and magnolol content as indexes. Four factors were chosen in this experiment, including alcohol consistence, the alcohol consumption, duration of extraction and times of extraction.The results showed that the optimal extraction process was 65% alcohol consumpted 8 times the amount of magnoliae cortex,refluxing for 3 times,each time 120 min.更多还原
