Determination of paeonol in huangliansu tablets by Capillary Electrophoresis

This design uses High Performance Capillary Electrophoresis (HPCE) to determine the Paeonol's content in huangliansu tablets. Electrophoresis separation controlled conditions for uncoated fused silica capillary column (75μm×52 /60cm) injection height 7.5cm, and using a concentration of 40 mmol/L borax solution as buffer. Using separate voltage 20KV to detect wavelength 270nm, temperature is 17℃, and the injection time control 10s. The Paeonol is linear relationship(r=0.998) within concentration of 3~400mg/L, Measured paeonol content in huangliansu tablets was 13.2 mg/g (RSD = 14.4%) (n = 6). The recovery of paeonol in huangliansu tablets sample was in the range of 73.1% - 118.1% (n=4).
