Abstract

Ten sesquiterpenens were isolated from Inula helenium. Among them, three eudesmanolides: 15‐hydroxy‐11βH‐eudesm‐4‐en‐8β,12‐olide (1), 3α‐hydroxy‐11βH‐eudesm‐5‐en‐8β,12‐olide (2) and 2β, 11α‐dihydroxy‐eudesm‐5‐en‐8β,12‐olide (3) are new compounds. Their chemical structures were determined by spectral methods including 2D NMR. Copyright © 2008 John Wiley & Sons, Ltd.
