| Objective：To develop an HPLC method for the determination of Desoxy-Palonosetron dihydrochloride,Epimer-Palonosetron Hydrochloride and N-Oxide-Palonosetron in Palonosetron Hydrochloride Injection. Method：The assay was performed on a Inertsil ODS-3 C18 column(4.6 mm×250 mm,5 μm) with sodium perchlorate buffer solution-acetonitrile(72：28)as mobile phase at the flow rate of 1.0 mL.min-1 ；The column temperature was 30 ℃ and detected with UV 210 nm. Results：The assay of Desoxy-Palonosetron dihydrochloride,Epimer-Palonosetron Hydrochloride and N-Oxide-Palonosetron was determined accurately under the selected HPLC conditions,and the methodological studies conformed to the requirements for analysis. Conclusion：The method can be used for the assay of three impurities in Palonosetron Hydrochloride Injection with high sensitivity,accurate and reliable results. |
