A high‐performance anion‐exchange chromatography coupled with diode array detection method was developed for the determination of dencichine in Panax notoginseng and related species. The analysis was performed on an Eprogen Synchropak WAX column (4.6 × 250 mm, 6 μm) with 50 mM NaH2PO4 aqueous solution isocratic elution. The method was validated in terms of linearity, sensitivity, precision, stability,...
