Objective: To establish a HPLC method for determining puerarin in Chaiqin soft capsules. Method: The HPLC analysis was performed on a C18 column (4.6 mm×250 mm
5 μm) with methanol-water-phosphoric acid (25: 75: 0.2) as mobile phase
detected at the wavelength of 250 nm. Result: Puerarinwas linear in the range of 0.559 5-111.9 mg · L-1(r=0.999 8). The average recovery was 99.85%
RSD 0.83%. the RSDs of precision and reproducibility were 0.52% and 0.57% respectively. Conclusion: The method is simple
accurate and reproducible
which can be used to determine puerarin in Chaiqin soft capsules.
