Objective: To optimize extraction technology of Dalianqiao capsule. Method: L9(34) orthogonal design was used to select optimum extraction technology.Yield of extract
yield of n-butanol extraction site
yield of ethyl acetate extraction part and the content of phillyrin were used as criteria.The content of phillyrin was determined by HLPC. Result: Optimal extraction technology was as follow:extracted 2 times with 8 times the amount of water for 2 h each time. Conclusion: This extraction technology was reasonable
