Objective: An HPLC method for simultaneous determination of four components in Buyang Huanwu Tang extract was established. Method: The Buyang Huanwu Tang extract was separated on an Hyperil ODS2 column by gradient elution using acetonitrile(A)-0.1% phosphate (B) as the mobile phase. The flow rate was 1.0 mL·min-1. The detection wavelengths were 210 (amygdalin)
230(paeoniflorin)
250(campanulin)
315 nm (ferulic acid). Result: The linear ranges of amygdalin
paeoniflorin
campanulin and ferulic acid were 1.080-10.80(r=0.999 8)
1.735-17.35 (r=0.999 8)
0.242-2.42 (r=0.999 5)
0.106-1.06 (r=0.999 6) μg
respectively;the average recovery was 98.39% (RSD 1.9%)
98.89% (RSD 2.0%)
97.25% (RSD 3.3%)
95.39% (RSD 2.6%). Conclusion: The method is rapid and accurate for simultaneous determination of amygdalin
paeoniflorin
campanulin and ferulic acid in Buyang Huanwu Tang extract.
