Objective:Optimization of water extraction process of rhizoma coptidis
cortex phellodendri and angelica was performed by uniform design.Method:Rhizoma coptidis
cortex phellodendri and angelica were extrac-ted with water by reflux.The content of berberine hydrochloride and dry paste were used as index to inspect the in-fluence of water multiple added
immersion time
extraction time and extraction numbers on extraction process
to de-termine the optimal water extraction technology.Result:The best water extraction technology was as follows:8 times of water
soaking 30 min
extracted for 60 min and extraction three times.Conclusion:The results can provide the basis for determination of water extraction process and the reform of dosage-form.
