Objective:To study the extraction and Purification of Shuxiong dropping pill.Methods:The extraction rate of ginsenoside Rg1 and the content of ferulic acid were used as the indices of evaluation

respectively

the extraction of Radix Notoginseng and the Purification of Rhizoma Chuanxiong and others were optimized by orthogonal tests.Results:The optimal conditions of the extraction and Purification of Shuxiong dropping pill were as follows: Radix Notoginseng was refluxed with 10 times of 75% alcohol

for 2 times

2 hours per time;the solution of water-extraction of Rhizoma Chuanxiong and others was concentrated to a relative density of 1.00～1.10(60 ℃) and then precipitated by alcohol at the concentration of 60%

then stewing 24 hours.Conclusion:The results may be used for reference for the preparation of Shuxiong dropping pill at a production scale.
