| Abstract: | Objective To establish an HPLC method for determination of benzoin acid and salicylic acid in tri-acides powder. Methods An Agilent Eclipse XDB C1s（4.6 mm × 150 mm,5 μm） was used by HPLC. The de- tection wavelength was 275 nm, the flow rate was 1 ml·min- 1, and the mobile phase was methanol-0.1% phosphor- ic acid（50： 50）. Results The linear range of benzoin acid and salicylic acid was 0.0578 -0. 4049 mg ·ml- 1 and 0. 1152 -0. 8066 mg ·m1-1 respectively. The recovery rate was 100.0% and 99.5% , respectively. Conclusion This method is simple and accurate in simultaneous determination of these two components, which can be used to control the quality of tri-acid powder. |
