| 摘 要： | 目的：建立杞菊地黄丸中丹皮酚的电化学检测方法。方法：循环伏安（CV）、差分脉冲（DPV）及高效液相色谱。结果：在0．1mol／L的NaOH—NaH2P04（pH=11）底液中、100mV／s的扫描速度下丹皮酚在铂电极上有一灵敏的氧化峰，峰电流与其浓度在5．0×10^-6～1×10^-3m0L／L的范围内呈良好的线性关系，线性回归方程为：I=0．22—4082．32×C（r=0．9972），检出限为1×10^-6mol／L。应用于杞菊地黄丸中丹皮酚的检测，结果令人满意。结论：该方法准确可靠，操作简便、快速，重现性好。

| Abstract: | Purpose ：The electric chemistry analysis method to measure paeonol in Qijudihuang Pills was established. Method： Cyclic Voltammetry, Differential Pulse Vohammetry and HPLC. Result： In 0. 1mol · L^-1 NaOH -NaH2PO4 buffer solution （ pH = 11 ）, a sensitive oxidization peak of paeonol was obtained. The peak current was directly propor - tional to the concentration of paeonol over the range of 1.0 × 10^ -5 - 1.0 × 10 ^-3 mol/L with the detection limit of 5 × 10 ^-6moL/L. Conclusions ： The method was applied to the determination of paeonol in Qijudihuang Pills with satisfactory results. Conclusion： This method was accurate and dependable, operating simple, fleetness, easily re -appear. |
