Determination of Curcumin in GanZhiPing Capsules by RPHPLC
Abstract:ObjectiveTo establish a simple and sensitive HPLC method for determining curcumin in GanZhiPing Capsules.MethodsCurcumin was separated on ODS column with a mobile phase of acetonitrlewater(7.6%acetic acid)(55∶45)and detected at 420 nm with a flowrate of 1 ml/min.ResultsThe calibration curve was linear within the range of 1.92~9.60 μg(r=0.9999 6).The averge recovery of curcumin was more than 98%.ConclusionThis method was simple and accurate method for the determination of curcumin in GanZhiPing Capsules.
