Objective: To optimize extraction process of crude drug from Fufang Yungui granules. Method: Using extraction rate of ferulaic acid from angelicae sinensis radix and naringin from aurantii fructus as indexes
HPLC was used to quantitative
optimized process of water extraction by L9(34) orthogoral design. Result: The optimum technology of water extraction was as follows: extracted twice with 12 and 10 times the amount of water
soaked 1 h
extracted 1.5 h each time. Conclusion: The optimum extraction technology is stable
feasible and suited for industrialization production.It can settle foundation for preparation of Fufang Yungui granules.
