ABSTRACT
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 μm) 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 °C, 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'-dihydroxy-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.
