Objective: To determine the content of chlorogenic acid in Jiangnian Capsules by HPLC. Method: Phenomenex C18 column (4.6 mm×250 mm
5 μm) was used. The mobile phase was methanol-0.2% phosphoric acid (20: 80) and the detecting wavelength was set at 327 nm; the flow rate was 1.0 mL·min-1
and the injection volume was 10 μL; the column temperature was kept at 30 ℃. Result: The linear range of calibration curve was 4.344-130.3 mg·L-1 for chlorogenic acid (r=0.999 8). The average recovery rate was 99.93% (RSD 0.12%). Conclusion: The method is highly sensitive
quick and accurate with good repeatability
which can be used for the quality control of Jiangnian Capsules.
