摘要

The quality of compound traditional Chinese medicine is the prerequisite and foundation for its stable efficacy. Based on the quality by design( QbD) concept,the controllable extraction times,extraction time and the ratio of water were the critical process parameters( CPPs) in the Tuomin Dingchuan Prescription extraction process. The CQAs corresponding to CPPs were screened from the four potential critical quality attributes( p CQAs),namely the extraction amount of solid matter,the content of amygdalin,the content of cimicifugoside and the content of 5-O-methylvisammioside by orthogonal experiment. The extraction amount of solid matter and the content of amygdalin were determined as CQAs in the extraction process by the variance analysis of Box-Behnken experimental. The optimal extraction process based on the linear model between CQAs and CPPs of the extraction process was immersion in water for 30 minutes,extraction for three times,extraction for 100 minutes each time and 10 times of water volume. The control space was established for the extraction amount of solid matter and the content of amygdalin,and both of them could be controlled simultaneously to achieve the optimization objective. The molding ratio of Tuomin Dingchuan granules was regarded as CQA in forming process. On the basis of the single factor investigation,the ratio of dry extract powder to excipient and the ratio of ethanol were determined as CPPs. The central composite design( CCD) was used to optimize the forming process of Tuomin Dingchuan granules. The results showed that the dextrin was used as the filler; the ratio of dry paste to dextrin was 1 ∶1; and 0. 3 m L·g-1 of 70% ethanol was added as binder. The soft material and granules conformed to the actual production requirements.
