Study on the Extractive Technology of Penyanling Granules

Objective To optimize the extraction process in Penyanling granules.Methods Water extraction technology for Penyanling granules was optimized by contrast test method and orthogonal test method.The orthogonal experimental design was applied with the content of salvianolic acid B,paeoniflorin,and the dry extract rate as investigative indexes for investigating the best extraction process.Results Optimum extraction technology was extracted 2 times,first time extrated 1.5 hours with 10 times the amount of water,second time extrated 1 h with 8 times the amount of water.Conclusion The optimized technology was stable,feasible and suitable for the extraction of Penyanling granules
