Objective To establish a method for determining thecontents of paeoniflorin, cinnamaldehyde and paeonol in Guizhi JiliuPills. Methods The RP-HPLC wavelength switching method was used, theanalysis was achieved on an ES Epic ${\mathrm{C}}_{18}\left({{4.6}\mathrm{\;{mm}}\times {250}\mathrm{\;{mm}},{5\mu}\mathrm{m}}\right)$ column, the mobile phase was acetonitrile-0.1% aqueous solution of phosphoric acid gradient elution, the flowrate was ${1.0}\mathrm{\;{mL}}/\mathrm{{min}}$ , thecolumn temperature was ${25}^{\circ }\mathrm{C}$ and thedetection wavelength were ${230}\mathrm{\;{nm}}$ $\left({0\sim {25}\mathrm{\;{min}}}\right),{290}\mathrm{\;{nm}}\left({{25}\sim {41}\mathrm{\;{min}}}\right)$ and ${274}\mathrm{\;{nm}}\left({{41}\sim {51}\mathrm{\;{min}}}\right)$ . Results The linear ranges of paeoniflorin, cinnamaldehyde and paeonolwere 3.6169~90.4232 μg/mL ( $r={0.9993}$ ),1.8388~45.9695 μg/mL ( $r={0.9999}$ ),2.0240~50.5994 μg/mL ( $r={0.9999}$ ). The average sample recovery rates were95.4%(RSD=1.2%), 93.0%(RSD=0.7%) and 94.2%(RSD=1.2%) respectively. Conclusion This method is accurate, sensitive, and has strong specificity. It can be used for the quality control of Guizhi Jiliu Pills.
