Objective To establish an HPLC method for the simultaneous determination of protocatechuic acid, hydroxysafflor yellow A, p-coumaric acid, erulic acid, β-ecdysterone, and tracheloside in Tangbi Tongluo Granules. Methods The analysis was performed on ACE 5 C18-AR column (250 mm×4.6 mm, 5 μm). The mobile phase was acetonitrile - 0.1% phosphoric acid solution with gradient elution. The detection wavelength was set at 260 nm (protocatechuic acid and β-ecdysterone), 280 nm (p-coumaric acid, ferulic acid, and tracheloside), 360 nm (hydroxysafflor yellow A). The flow rate was 1.0 mL/min, temperature of column was set at 40 ℃, and the volume of injection was 5 μL. Results Protocatechuic acid, hydroxysafflor yellow A, p-coumaric acid, erulic acid, β-ecdysterone, and tracheloside showed good linear relationships within their respective linear ranges (r ≥ 0.999 5), whose average recoveries were 103.63%, 96.93%, 103.18%, 97.09%, 102.38%, and 100.08% with RSD values of 1.01%, 0.88%, 1.27%, 0.90%, 1.35%, and 1.05%, respectively. Conclusion The method is simple accurate, stable reliable, and repeatable, which can be used to control the quality of Tangbi Tongluo Granules.
