				        	Objective To establish a RP-HPLC method investigate the processing technique and mechanism of Eucommiae Cortex.Methods The RP-HPLC method was applied to simultaneously determining six ingredients,geniposidic acid,geniposide,genipin,chlorogenic acid,(+)-pinoresinol-di-β-D-glucopyranoside,and(+)-syringaresinol-di-β-D-glucopyranoside,in the different processed barks of Eucommia ulmoides.Results The valid method with good accuracy could be well used to study the processing technique of E.ulmoides;Besides,target ingredients in E.ulmoide were decreased within 6 h when they were processed.Conclusion Established RP-HPLC is a reliable method which could be used to research the processing technique of the barks ofE.ulmoides.Moreover,the result of this study could be provided with significant evidence of processed barks of E.ulmoides.
