| Abstract: | Objective: To establish a method to determine Vitamin C in the Vc Yinqiao Tablets. Method: Diffuse Reflectance in FTIR was used to determination of Vitamin C in the Vc Yinqiao tablets.Result: The content of Vitamin C could be obtained directly,and the relationship between the absorbance and the concen tration was linear. The average recovery rate of Vitamin C was 98.69%, and RSD was 0.33%. Conclusion: The method is simple, accurate and reliable, which may well be used for the determination of Vitamin C in the Vc Yinqiao Tablet. |
