Abstract:Objective: To investigate the extraction process of total alkaloids from Corydalis yanhusuo. Methods: The extraction process of total alkaloids from Corydalis yanhusuo was optimized by L9(34) orthogonal experiment with the contents of total alkaloids and tetrahydropalmatine as the index which were determined by UV and HPLC. Results: to investigate the effects of extraction time, concentration alcohol, extraction times and solvent volume on the extraction of the total alkaloids of yanhusuo: The optimal extraction process was: adding 8 times of 60% alcohol, refluxing and extracting for 3 times, 1.5 h per time. Conclusion: The optimal extraction process of Corydalis yanhusuo is simple, and practical for industrial production.
