OBJECTIVE: To establish a method for simultaneous determination of danshensu, salvianolic acid B, protocatechuic aldehyde, paeoniflorin and ferulic acid in Jingzhi guanxin granule. METHODS: HPLC was performed on the column of Zorbax Eclipse XDB-C18 with mobile phase of acetonitrile-methanol -0.5% H3PO4(gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 280 nm (for danshensu, protocatechuic aldehyde, salvianolic acid B),230 nm (for ferulic acid) and 320 nm (for paeoniflorin), column temperature was 30 ℃,injection volume was 10 μl. RESULTS: The linear range was 1.19-478.34 μg/ml for danshensu(r=0.999 9), 0.11-44.93 μg/ml for protocatechuic aldehyde(r=0.999 9),7.49-995.20 μg/ml for salvianolic acid B(r=0.999 7), 0.95-379.39 μg/ml for paeoniflorin (r=0.999 9) and 0.01-3.12 μg/ml for ferulic acid (r=0.999 5); the limits of quantitation were 1.91 ng, 0.36 ng, 150.00 ng, 2.74 ng and 0.10 ng, limit of detection were 0.96 ng, 0.10 ng,45.00 ng,1.52 ng and 0.03 ng; RSDs of precision, stability and reproducibility tests were lower than 2%; recoveries were 98.06%-99.47% (RSD=0.52%,n=6), 98.01%-99.49% (RSD=0.70%,n=6), 98.44%-99.45% (RSD=0.37%,n=6), 96.94%-100.71% (RSD=1.27%,n=6) and 95.44%-100.44% (RSD=1.90%,n=6). CONCLUSIONS: The method is simple and accurate, and suitable for the simultaneous determination of danshensu, salvianolic acid B, protocatechuic aldehyde, paeoniflorin and ferulic acid in Jingzhi guanxin granule.
