Objective: To optimize extraction process of Sanhu Tongfeng granule. Method: Orthogonal design was used to investigate the amount of water
extraction times and extraction time with the content of polydatin
emodin and yield of extract as indexes. The content of polydatin and emodin were determined by RP-HPLC
yield of extract was determined by drying method. Result: The best extraction conditions were as follows:refluxing extracted 2 times with 10-fold water
1 h for each time. Conclusion: This optimized extraction process was reasonable
