The genus of Artemisiae was used either health food or medicinal plant for the treatment of stomachache, fever, pain, asthma, enteritis, and bronchitis. In this study, we developed an HPLC/PDA method by using seven marker compounds [chlorogenic acid (1), hyperoside (2), 3,4-di-O-affeoylquinic acid (3), 3,5-di-O-caffeoylquinic acid (4), 1,5-di-O-caffeoylquinic acid (5), 4,5-di-Ocaffeoylquinic acid (6) and eupatilin (7)]. Seven marker compounds were well separated with a Kinetex C18 (250x4.6 mm, 5 �¼m) by gradient elution using 0.3% formic acid in water and acetonitrile as mobile phase. The flow rate was 1.0 mL/min and the UV detector wavelength was set at 327 nm. The method was successfully used to distinguish between Artemisiae argyi Folium and Artemisiae iwayomogi Herba by qualification of these marker compounds 1-7. Furthermore, this method also evaluated the linearity, recovery, precision, accuracy, stability and robustness. In conclusion, the results revealed the successful identification of the two herbal species according to qualification of seven marker compounds (1-7).
