Objective: To set up the determination of total bufadienolides content in cinobufotalin injection by UV. Method: A rapid and validated method was established for the determination of total bufadienolides in cinobufacini injection using ultraviolet spectrophotometry. Result: Total bufadienolides in cinobufacini injection were analyzed with acceptable linear regression relationship from 6.4 to 32 μg.The regression equation was Y=0.005 66X+0.027 6(r=0.999 9).Five batches of cinobufacini injection were included in the analysis.The content of total bufadienolides was from 4.62 to 5.80 mg·L-1. Conclusion: A simple method with good repeatability was established
which was benefit for the quality control of total bufadienolides in cinobufacini injection.
