| Abstract: | Objective To establish a supplementary detection method for determining adulterant potassium salt in Flos Lonicerae and Flos Lonicerae Japonicae. Methods Flame type： air/ethine; potassium hollow cathode lamp was used. Potassium was detected at the wavelength of 766.5 nm. The flow rate of acetylene gas： 1.7 L/min; the flow rate of air： 13.5 - 15.0 L/min; slit： 2.0 nm. Results The linear range for potassium was 0. 263 2 - 2. 632 μg/mL （ r = 0. 999 02）. The average recovery rate was 98.48%, RSD = 1.44%. Conclusion The method is simple, rapid, accurate and reproductive, which can be used for the determination of potassium salt in Flos Lonicerae and Flos Lonicerae Japonicae. |
