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.
