Objective:To optimize water extraction technology of Qijiao ointment. Method:With astragaloside and water extracts as indexes
HPLC-ELSD was used to determined the content of them
water extraction technology was optimized by orthogonal design
extraction times
extraction time and the amount of water were investigated as factors. Result:Optimal water extraction process of Qijiao ointment was:added 8 times the amount of water
decocting for three times
1 h each time. Conclusion:This optimized technology was stable and feasible
it showed high yield of astragaloside in Qijiao ointment.
