Objective To optimize the condions for the extraction of Fructus leonuri.Methods Conditions for the extraction were studied by orthogonal experimental design as guided by the content of stachydrine present in the extract.Results Significant effect was observed in times of extraction.Conclusion The optimum condion of Fructus leonuri was to be in a stata of hot reflux with six times of 50% ethanol for there times
