OBJECTIVE
To optimize the best extraction condition of semi-bionic extraction for licorice.
METHODS
The best extraction condition of the semi-bionic extraction for licorice by uniform design was optimized with glycyrrhizic acid, total flavonoids, total polysaccharides, total HPLC integrate area and dried extract weight as the indexes.
RESULTS
The optimized technologic condition: The pH values of the water for the 1st, 2nd, and 3rd decoctions were in order of 5.88, 7.50, and 8.90, and the total extraction time was 3.93 h.
CONCLUSION
According to industry production condition, the best SBE technologic condition is: The pH values of the water for the 3 decoctions are in order of 6.0, 7.5, and 9.0, and the extraction time are 2h, 1h, and 1h, respectively.
目的
优化甘草半仿生提取的最佳条件。
方法
以甘草酸、总黄酮、总多糖、高效液相色谱总积分面积和干浸膏重量为指标，采用均匀设计法优化甘草半仿生提取的最佳条件。
结果
优化工艺条件为：第一次、第二次、第三次水煎液的pH值依次为5.88、7.50、8.90，总提取时间为3.93小时。
结论
根据工业生产条件，最佳半仿生提取工艺条件为：三次水煎液的pH值依次为6.0、7.5、9.0，提取时间分别为2小时、1小时、1小时。
