ABSTRACT
Objective:
To improve the quality control level of ethanol extraction process of Corydalis Rhizoma (CR) by using quality by design (QbD), so as to meet the extraction requirements of Kedaling Tablets.Methods:
The critical process parameters were solvent multiple, extraction time and soaking time, and the critical quality attributes were dry extract rate, content and transfer rate of dehydrocorydaline. The response surface methodology was used to establish the mathematical model between the critical process parameters and the critical quality attributes. The overlapping design space of multiple index design spaces was established to select the optimal operation space, where the process verification was carried out.Results:
The operating space parameters of ethanol extraction of CR was 14-24 h of the immersion time, 3.0-4.0 times of the first time solvent multiple, 1.5-2.0 times of the second and third time solvent multiple, and 1.5-2.5 h of the extraction time. Under this operating space, the extraction yield of CR was ranged from 6%-8%, the content of dehydrocorydaline was more than 2.8%, and the transfer rate was not less than 85%.Conclusion:
The concept of QbD is helpful to improve the ethanol extraction process of CR, and to obtain a reliable and suitable extraction operation space for the production of Kedaling Tablets.
