Abstract:
Objective To optimize the extraction technology of Zhiqian Capsule;To provide evidence for researches on preparation into new Chinese medicine. Methods The main influential factors of extraction technology included the quantity of water, extraction time and immersion time. The extraction effect was evaluated with the content of aesculetin and the extract yield as indexes. The optimal extraction technology of Zhiqian Capsule was selected by single factor experiment and central composite design-response surface method. Results The best extraction conditions were as follows:reflux extraction for twice, the first time adding 10-fold of water and extraction for 2.5 h, the second time adding 8-fold of water and extraction for 2 h. Conclusion The optimal extraction technology of Zhiqian Capsule is efficient for extracting aesculetin, as well as economical, reasonable, easy and feasible.
