Objective:To optimize extraction technology of Qingfang Tongyu powder. Method: Based on single factor experiment
used the content of sinomenine and tetrandrine
the amount of solids as indexes
extraction technology of Qingfang Tongyu powder was optimized by orthogonal experiment. Result: Optimum extraction technology was:refluxing extracted 2 times with 8 times of the amount of 70% ethanol with 1.5 h each time. Conclusion: This optimum extraction technology was stable
