Optimization of Extraction Process for from Yuanhu Zhitong Soft Capsule
Objective: To optimize extraction process of Corydalis yanhusuo from Yuanhu Zhitong soft capsule. Method : With the content of tetrahydropalmatine as an indictor by HPLC
L9(34) orthogonal test was used to investigate influencing factors
such as the concentration of ethanol
the amount of ethanol
extration times
extraction time and so on. Result :Optimized extraction technology was:extracted 3 times with 6 times the amount of 70% ethanol
each time 1.5 h.RSD of three batches of validation tests was 2.60%. Conclusion :This optimized extraction pocess of C. yanhusuo from Yuanhu Zhitong soft capsule was stable and available.
