Abstract
Objective: To establish the quality standards for the preparation of Xiao’er Qingre enema in hospitals. Method:Thin-layer chromatography (TLC) was used to identify Radix Isatidis and Glycyrrhizae in the prescription. The content of (R,S)-Goitrin was determined by high-performance liquid chromatography (HPLC). Results: In TLC identification, there was no interference between the negative controls of Radix Isatidis and glycyrrhizae, and the spots were well-separated. The HPLC results of (R,S)-Goitrin showed a good linear relationship between the peak area and concentration within the range of 0.476–95.2 μg·mL-1 (r = 0.9999). Conclusion: The TLC and HPLC methods established in this experiment are simple, reproducible, and specific, making them suitable for the quality control Xiao’er Qingre enema preparation in hospitals.
