Abstract:
Objective To optimize the extraction conditions for Yuemu eye drops.Methods The extraction conditions were studied with orthogonal test L_9(3~4),the content of caffeic acid was determined by HPLC as index.Results Alcohol concentration and frequency of extraction were remarkable factors in the test. Conclusion The optimum extraction technology for Yuemu eye drops was to reflux and extract the materials for 2 times in 80% alcohol,the volume of which was 6 times the weight of herbal medicine,with 1 hour for each time.
