Objective To study the chemical constituents in the aerial parts of Eupatorium odoratum. Methods The compounds were isolated and repeatedly purified by chromatography on silica gel, MCI, RP-18, and Sephadex LH-20 columns, and their structures were elucidated on the basis of spectral analyses. Results Twenty compounds were obtained and identified as odoratin (1), kaempferol (2), kaempferol-4′-methyl ether (3), quercetin (4), dillenetin (5), isorhamnetin (6), luteolin-4′-methyl ether (7), 3, 4′-dihydroxy-5, 6, 7-trimethoxyflavone (8), scutellaretin tetramethyl ether (9), acacetin (10), isosakuranetin (11), 4′-hydroxy-5, 6, 7-trimethoxy- flavanone (12), 5, 6, 7, 4′-tetramethoxyflavanone (13), dihydrokaempferide (14), aromadendrin-7, 4′-dimethyl ether (15), naringenin- 7, 4′-dimethyl ether (16), 5, 6, 7-trihydroxy-4′-methoxyflavanone (17), 5, 6, 7, 3′, 4′-pentamethoxyflavanone (18), 1-glycerol- hexadecylate (19), and β-sitosterol (20), respectively. Conclusion Compounds 6—9 and 16—19 are obtained from the plant for the first time.
