Objective:To Study the optimal extracting techniques of Ruyi-jinhuang plaster.Methods:By using of contents of berberine and minimal lihibitory concentration as indexes
the conditions of extracting volatile oil
alcoholic concentration and extracting time were determined with orthogonal design method.Results:The optimal extracting conditions are as follows:using 90% alcohol as extracting solvent to extract for two times
the first times for 2 hous and second times for 1 hour.Conclusion:The optimal technique is stable and high efficient.
