ObJective: To establish a method for determination of plumbagin in ZiJintougu sprays. Method: The column was Elipse-XDB-C18 (4.6 mm×150 mm
5 μm) and the mixture of methanol-water (70 ∶30) was used as mobile phase; the detection wavelength was at 406 nm. Result: The linearity was in the range of 0.046-0.410 μg (r=0.999 9). The average recovery was 99.96% with RSD of 1.86%. Conclusion: The method was simple
rapid and accurate
and suitable for the quality control of ZiJintougu sprays.
