ABSTRACT
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.
