| Abstract: | Objective: To optimize ultrasonic extraction technology of caffeic acid and rosmarinic acid from Isodon lophanthoides. Method: A HPLC method was established to determine the content of caffeic acid and rosmarinic acid in I. lophanthoides.With yield of caffeic acid and rosmarinic acid as indexes,based on single factor test,extraction technology was optimized by L9(34) orthogonal test by screening extraction solvent,material-liquid radio,extraction time as factors. Result: Optimal ultrasonic extraction conditions were as follows:extracted 40 min with 20 times the amount of 30% ethanol. Conclusion: This optimized extraction technology was simple and economical with high extraction rate,it could provide a reference for development and utilization of I. lophanthoides. |
