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