Determination of retinol palmitate,colecalciferol and vitamin E acetate in multi-vitamin injection by solid phase extraction and RP-HPLC

  • School of Pharmacy, Guangdong Medical College, Dongguan 523808, China

  • Received Date: 2006-06-27
  • Objective: To establish nonaqueous RP-HPLC to determine retinol palmitate、colecalciferol and vitamin E acetate in multi-vitamin injection simultaneously. Methods: The fat vitamins were extracted by SPE; The determination was performed on Warters C18 column (150×4.6 mm, 5.0 μm) with the mobile phase of acetonitrile-methanol-dichloromethane(702010),at a flow rate of 1.0 mL/min and the detection wavelength of 265 nm.Results: In the linear range the correlation coefficients were all 0.999 9.The average recoveries of retinol palmitate、colecalciferol and vitamin E acetate were 99.1%, 100.6% and 99.2%, RSDwere 0.19%, 0.79% and 0.52%.Conclusion:The method is simple and rapid, suitable for the analysis of retinol palmitate,Colecalciferol and vitamin E acetate in multi-vitamin injection.
