Abstract
OBJECTIVE To optimize the extraction technique of Tongliding cataplasm.METHODS The extraction technique was optimized by L9(34)orthogonal experimental design and the content of emodin was used as the inspecting mark.RESULTS The optimal extraction technique were: amount of 90% ethanol was 8 times of medicinal material,soping for 48h and the flow rate was 2mL·(min·kg)-1.CONCLUSION The extraction technique was stable and feasible.
