| Abstract: | Objective:To optimize flash extraction technology of fresh Rehmannia glutinosa. Method: With catalpol and yield of dry extract as indexes,extraction time,extraction times and solvent consumption were chosen as factors,flash extraction technology of fresh R. glutinosa was optimized by orthogonal test and single factor test.The content of indicator ingredients was determined by HPLC. Result: Optimum flash extraction process was:extrated 1 times with 3 times the amount of 95% ethanol,extraction time of 3 minutes. Conclusion: This optimized process was fast,scientific and reasonable. |
