Optimization of extraction process of Shengyang Huazhuo Jiangtang Formula based on multi-index comprehensive evaluation
Objective To optimize the extraction process of Shengyang Huazhuo Jiangtang Formula.Methods Orthogonal experimental design was used,the comprehensive scores of the content and solid quality of nine components,including mononoside,loganin,paeoniflorin,glycyrrhizin,glycyrrhizic acid,piloside,icariin,rutaecarpine,and rutaecarpine,were used as evaluation indicators.The extraction frequency,extraction time,and water addition were investigated to determine the optimal extraction process.Results The determined process as follows,extracting for 3 times,each time for 1 hour,adding 10 times the amount of water for the first time,and adding 8 times the amount of water for the second and third times.The average comprehensive score of the three batches of validation tests was 90.11.Conclusion The optimized process is stable and feasible,which lays a foundation for the follow-up research and development of Shengyang Huazhuo Jiangtang Formula.
