Abstract A liquid chromatographic method was developed and validated for the determination of ginsenosides in Panax ginseng roots by using evaporative light-scattering detection. Eighteen ginsenosides were separated on a reversed-phase C18 column with water–ammonium acetate–acetonitrile as the mobile phase. The method is suitable for the routine determination of ginsenosides in P. ginseng roots and extracts. The validation of the method was comprehensive for efficiency and recovery optimization of the P. ginseng roots extraction, specificity by liquid chromatography/mass spectrometry, linearity, stability, reproducibility, repeatability, intermediate precision, and robustness.
