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 extracted with water by reflux.The content of berberine hydrochloride and dry paste were used as index to inspect the influence of water multiple added
immersion time
extraction time and extraction numbers on extraction process
to determine 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.
