Abstract
Objective: To determine the related substances of Vinpocetine Injection by HPLC. Method: The separation was performed on Hypersil ODS C18 column (4.6 mm×150 mm
5 μm). The mobile phase consisted of methanol-1.75 g·L-1 ammonium carbonate solution-acetic acid (80:25:3)
the flow rate was set at 1.0 mL·min-1 with detection at 273 nm. Result: Under the established chromatographic conditions
the related substances and vinpocetine were separated completely. The detective limit was 20 ng.The precision in a day was good (RSD 0.52%). Conclusion: The method is simple
accurate
specific and sensitive for the determination Vinpocetine Injection related substances.
