Abstract: To determine the contents of Aspirin eugenol ester microemulsion(AEE-ME) and the related substances in AEE-ME, RP-HPLC method was used. The high performance liquid chromatographic conditions were as followed: ODS column (4.6 mm×100 mm,5 μm) was used as stationary phase and methanol-water (70∶30) was used as mobile phase; the detection wave length was 279 nm; lowing rate was 1.0 mL/min; temperature was 30 ℃. The calibration curves was a good linearity in the range of 1.25 to 40 μg/mL for AEE at 279 nm(r=0.9923),the average recovery rate was 99.93%, and RSD was0.84%. The results showed that the method was suitable for detection of the content and the related substances of Aspirin eugenol ester and could be used in quality control.

Key words: Aspirin eugenol ester; microemulsion; RP-HPLC; content determination
