目的:建立色差计测定注射用益气复脉(冻干)溶液颜色的方法。方法:以黄色标准比色液为标准,测定测定注射用益气复脉(冻干)溶液颜色,考察方法的精密度、重复性和稳定性,并采用该方法对20批注射用益气复脉(冻干)进行检测。结果:本文所用色差法测定益气复脉(冻干)溶液颜色方法学考察结果满意,对20批样品进行检测效果良好。结论:色差计法测定注射用益气复脉(冻干)溶液颜色精密度高、重复性和稳定性好,值得采用。
Objective: To establish a method of colorimetric determination of injection of Yiqi Fumai (lyophilization) solution color. Methods: The standard colorimetric solution was used as the standard. The color of the solution for injection of Yiqi Fumai (lyophilized) was determined. The precision, repeatability and stability of the method were investigated. Lyophilized) for testing. Results: The colorimetric method of colorimetric method for determination of Yiqi Fumai (lyophilized) solution used in this paper was satisfactory, and the test results of 20 batches of samples were satisfactory. Conclusion: The colorimetric method for determination of Yiqi Fumai (lyophilized) solution for injection has high color precision, good reproducibility and stability, and is worth using.
