- Abstract: In this paper, an HPLC-QqQ-MS method for determination of 5 different ginsenosides of Panax japonica collected from different cultivated geographic regions was established. The separation was performed on a Zorbax XDB-C₁₈ (4.6 mm×100 mm, 1.8 μm) column with the gradient elution of acetonitrile (contained 0.1% formic acid)-0.1% formic acid water. The flow rate was 0.5 mL•min⁻¹. The colunm temperature was maintained at 30 ℃. The analytes were detected using electrospray ionization (ESI) in multiple reaction monitoring (MRM) modes. Reaction selected ions were 203.2 for ginsenoside Re, 202.9 for ginsenoside Rg₁, 365.0 for ginsenoside Rf, 789.1 for ginsenoside Rd, 360.9 for ginsenoside Ro. Ginsenosides Re, ginsenosides Rg₁, ginsenosides Rf, ginsenosides Rd, ginsenosides Ro had good linearity in the ranges of 3.33-66.60 μg (r=0.999 1),2.83-56.54 μg (r=0.999 2), 0.32-6.51 μg (r=0.999 2), 12.55-251.00 μg (r=0.999 3), 0.85-16.90 μg (r=0.999 5), respectively. The results of recovery were among 100.8% to 104.6%, and the values of RSD were blow 3.0%. This method is simple, reliable and accurate, and can provide basis for P. japonica basic research.
