Objective: To optimize extraction technology of Jinshui Ditan oral liquid. Method: Single factor tests were adopted to optimize extraction technology of aromatic water with extraction rate of volatile oil as index.With composite score of extracting amounts of hesperidin and icariin

yield of dry extract as index

orthogonal test was adopted to investigate effects of the amount of water

decocting time and times on extraction process.HPLC was employed to determine contents of hesperidin and icariin. Result: Aromatic water extraction process was distilled 4 hours with 10-fold water at a speed of 2 seconds per drop

then distilled 2 hours from aromatic water at the same speed

the final volume of distilled fragrance water was about 1.1 times weight of medicine.Water extraction technology was as follows:decocted thrice with 8-fold water

each time for 1.5 hour;extracting amounts of hesperidin and icariin were 27.77

15.30 mg · g-1

yield of dry extract was 40.13%. Conclusion: These optimized processes are stable and feasible

they can provide a reference for industrial production of Jinshui Ditan oral liquid.
