Objective: To establish a high-performance liquid chromatographic method (HPLC) for the simultaneous determination of 16 compounds from Artemisia ordosica. Methods: HPLC was used to analyze 16 quality indicators of A. ordosica. The HPLC conditions were as follows: Agilent Eclipse Plus C18 column (250 mm × 4.6 mm, 5 lm) with acetonitrile (A)-water (B) as mobile phase, gradient elution: 0–10 min, 75%–65% B; 10–30 min, 65%–35% B; and finally 30–40 min, 35%–15% B. The flow rate was 1.0 mL/min, the column temperature was 40 ℃, the injection volume was 10 μL, and monitored by absorbance at 285 nm for compounds 1–10, 12 and 225 nm for compounds 11, 13–16. Results: Under the selected experimental chromatographic conditions, compounds 1–16 showed good linearity (r > 0.9993) in a wide concentration range. Their average recoveries were 99.50%, 95.38%, 97.75%, 96.00%, 98.20%, 97.50%, 95.50%, 99.33%, 96.75%, 96.50%, 98.50%, 97.83%, 99.20%, 95.33%, 97.33% and 96.30%, respectively, and the RSD were 1.99%, 1.81%, 1.63%, 1.98%, 1.67%, 1.92%, 1.74%, 1.67%, 1.90%, 1.72%, 1.88%, 1.83%, 1.79%, 1.76%, 1.81% and 1.96%, respectively. Conclusion: Based on the results of the HPLC analysis, it was concluded that p-hydroxycinnamic acid (1), O-hydroxycinnamic acid (2), coniferyl alcohol (5), 5,4′-dihydroxy-7,3′-dimethoxyflavanone (8), 5,4′-dihy droxy-7-methoxyflavanone (9), 5-hydroxy-7,4′-dimethoxyflavanone (12), dehydrofalcarindiol (13), arteordoyn A (14), dehydrofalcarinol (15) and capillarin (16) are best suited for the role of quality indicators of A. ordosica grown in different ecological environments.
