Abstract

A new sequiterpenoid compound 8aα‐hydroxy‐1‐isopropyl‐4,7‐dimethyl‐1,2,3,4,6,8a‐hexahydro‐naphthalene‐2,6‐dione (1), together with seven known compounds anti‐HH‐dimer‐coumarin (2), (−)‐5‐exo‐hydroxy‐borneol (3), O‐hydroxyl cinnamic acid (4), 9β‐hydroxy‐ageraphorone (5), 10Hα‐9‐oxo‐ageraphorone (6), 10Hβ‐9‐oxo‐ageraphorone (7) and 9‐oxo‐10,11‐dehydroageraphorone 8, was isolated from the leaves of Eupatorium adenophorum Spreng. The structures were elucidated by IR, 1H and 13C NMR, EIMS, HMBC and single‐crystal X‐ray spectral data.
