Abstract:
OBJECTIVE:To establish a method for simultaneous determination of danshensu,salvianolic acid B,protocatechu-ic 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 detec-tion 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.
