OBJECTIVE: To establish a new extraction process optimization method based on the dynamic process of extract concentration during extraction. Methods: Taking the notoginseng as an example, we compared the content of indicator components, the extraction rate of total solids and the similarity of fingerprints in the orthogonal design optimization process and the dynamic process optimization process to evaluate the feasibility of the dynamic process optimization method. Results: The difference between the content of indicator components and the total solid yield was less than 5%, and the similarity of fingerprints was 100%. The results showed that the extracts from the two kinds of optimization processes were basically the same, and the dynamic process optimization process could save 79% of the extraction time. Conclusion: In terms of extraction time, the dynamic process optimization process is superior to the orthogonal design optimization process, which can greatly reduce the extraction time and reduce the production cost, which deserves to be popularized on a large scale.
