| Abstract: | Objective: To determine the content of total chlorogenic acid in Qingying injection. Methods: Ultraviolet spectrophotometry was employed to determine the absorbance at wavelength 324nm. Then the content was calculated by absorption coefficient of chlorogenic acid. Results: The average content of total chlorogenic acid is 19.38 mg/ml. Conclusion: This method is simple, rapid, and stable, with good precision,reproducibility, and recovery. It can be used for quality control in production process of Qingying injection. |
