Objective To study the chemical constituents in the ethyl acetate extract from Artemisia selengensis. Methods The chemical constitunents were isolated by various column chromatographic methods. The structures of the compounds were elucidated on the basis of physiochemical properties and spectral analyses. Results Eleven compounds were identified as trans-resveratrol (1), trans-cinnamic acid (2), caffeic acid (3), chlorogenic acid (4), gallic acid (5), luteolin (6), isorhamnetin (7), 7-methoxy coumarin (8), quercetin (9), acteoside (10), and 7-methoxy-4'-hydroxyisoflavone (11). Conclusion Compounds 1—11 are isolated from A. selengensis for the first time.
