Abstract: 【Objective】 The study was to determine the related substances of aspirin eugenol ester (AEE) chewable tablets by high performance liquid chromatography (HPLC), and establish a more convenient and accurate detection method for the quality control of AEE chewable tablets.【Method】 The specificity, linear range, limits of detection and quantification, precision, repeatability, stability, recovery, destructive testing, durability testing, and sample determination were investigated by HPLC, in order to comprehensively evaluate the determination method of related substances in AEE chewable tablets, and calculate the content of related substances by self-contrast method.The chromatographic separation was performed using a Phenomenex Luna C18 column (150 mm×4.6 mm, 5 μm) at 35 ℃.The mobile phase consisted of water containing 0.5% phosphoric acid (A) and acetonitrile (B) with gradient elution.The flow rate was 1.0 mL/min, the detection wavelength was 279 nm, and the injection volume was 10 μL.【Result】 The results showed that the HPLC method of AEE chewable tablets had high specificity, and the detected peaks were well separated from other peaks.The linear relation between peak area and concentration of the AEE was good in the range of 0.26-26.00 μg/mL, R2=1 (n=7).In addition, the linear relation between peak area and concentration of the impurity A was well in the range of 0.25-25.50 μg/mL, R2=0.9996 (n=7).The limits of quantification of AEE and impurity A were 0.52 and 0.51 μg/mL, and the limits of detection were 0.26 and 0.25 μg/mL, respectively.The relative standard deviation (RSD) of precision was less than 1%.RSD of intraday repeatability, daytime repeatability and stability were 0.88%, 2.50% and 1.84%, respectively.Average recovery was 100.14% (n=9, RSD=1.66%).Destructive test showed that material was basically conserved under different destruction conditions, and the material conservation was between 95% and 105%.The durability test showed that the durability of the detection conditions was good, RSD was 1.87%.In the three batches of samples, the content of impurity A in AEE chewable tablets was less than 0.5%, and the total impurity content was less than 1.0%.【Conclusion】 The method was validated to be simple, specific, accurate and suitable for the determination of related substances in AEE chewable tablets.
