目的:建立清咽喷雾剂的质量控制方法。方法:采用薄层色谱法鉴别其中玄参、金银花、黄芩;采用液相色谱法测定其中穿心莲内酯的含量。结果:玄参、金银花、黄芩的薄层色谱法鉴别方法有良好的重现性、专属性;穿心莲甙内酯在48.1~240.3μg.mL-1浓度范围内线性关系良好(r=0.9999),平均回收率为100.1%(RSD=0.32)。结论:该方法可用于清咽喷雾剂的质量控制。
Objective: To establish a quality control method for Qingyan spray. Methods: TLC was used to identify Scrophulariae, honeysuckle and Astragalus membranaceus. The content of andrographolide was determined by liquid chromatography. Results: The method for the identification of Scrophulariae scrophulariflora, honeysuckle, and Scutellaria baicalensis has good reproducibility and specificity; the linearity of the terpene lactone in the concentration range of 48.1-240.3 μg.mL-1 is good (r=0.9999). The average recovery was 100.1% (RSD = 0.32). Conclusion: This method can be used for the quality control of Qingyan spray.
