HPLC separation and determination of bufadienolide in Cinobufacini Injection / 中成药

ABSTRACT

Objective: To determinate the content of bufalin,resibufogenin and cinobufagin in Cinobufacini Injection. Methods: Liposoluble components in cinobufacini were extracted with ethyl acetate and determined by HPLC using a C 18 column, acetonitrile water(50∶50) as a mobile phase and UV detection wavelength at 299nm. Results: The method showed the good resolution, high sensitivity, satisfactory accuracy and specificity. Quantitatively analyze results showed that the concentration of bufalin, cinobufagin and resibufogenin in Cinobufacini Injection were 0.333 ?g?mL -1 , 0.159?g?mL -1 and 0.110?g?mL -1 , respectively. Conclusion: Bufalin in Cinobufacini Injection reached effective concentration, which was regarded as one of anti cancer components.
