摘要：

The aerial parts of the Texas bitterweed Hymenoxys odorata yielded five guaianolides, four pseudoguaianolides, five modified pseudoguaianolides and one aliphatic lactone. Ten of these compounds, hymenovin B and C, hymenolane B, hymenoratin B-G and the aliphatic lactone, 3β-hydroxyicosan-1, 5β-olide were previously unreported. The known lactones are hymenoxon, hymenolane, hymenoratin, hymenograndin and florilenalin. Structures, including stereochemistries, were elucidated by NMR and NOE experiments. The structure of hymenoratin D was established by X-ray analysis. © 1990.
