Objective: To optimize the extraction conditions of Xiao’er Fuxie navel patch. Method: Single factor and orthogonal experimental design was used to optimize extracting technology of Xiao’er Fuxie navel patch with the content of rutaecarpine as index. Result: The extraction time of essential oil in the Prescription was 2.5 h; the optimum extraction conditions of Non-volatile active ingredients were reflux extracting 2 times for 1 h each time with 8 times the amount of 70% ethanol. Conclusion: The process validation tests showed that the optimized extraction of Xiao’er Fuxie navel patch was efficient
