Abstract:
This study was aimed to establish a method for simultaneous determination of seven anions and organic acids in Huo-Xue Tong-Luo (HXTL) injection by HPCE. With tartaric acid as the internal standard, separation was performed on an uncoated fused silica capillary (50 μm × 64. 5 cm, 56 cm of effective length). The 14 mmol·L-1 potassium acid phthalate and 0.1 mmol·L-1 hexadecyl trimethyl ammonium chloride were selected for the running buffer solution (pH 5.6). The separation voltage was -16 kV. The detection wavelength was set at 210 nm. The column temperature was maintained at 25 ℃ . The sample was injected at 50 mbar×4 s. The results showed that
calibration curves of chloride ion, sulfuric acid root ion, formate ions, malic acid, succinic acid, iodate ion and acetic acid ions showed good linear relationship 41.4-248.2 μg·mL-1 (r = 0.999 3), 12.5-74.8 μg·mL-1 (r = 0.999 8), 18.2-109.1 μg·mL-1 (r = 0.999 8), 20.3-121.6 μg·mL-1 (r = 0.999 5), 17.2-103.1 μg·mL-1 (r=0.999 1), 17.6-105.6μg·mL-1 (r=0.999 6), 51.6-309.6μg·mL-1 (r=0.999 7), respectively. The average recoveries were 102.6%, 97.3%, 102.2%, 99.0%, 99.2%, 97.8%, and 103.4%, respectively. The RSD were 1.7%, 2.0%, 1.6%, 2.6%, 2.1%, 2.9%, and 1.0%, respectively (n = 6). It was concluded that the method was accurate and reproducible. It was suitable for the determination of anions and organic acids in HXTL injection.
