A new sequiterpenoid compound 8a α ‐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 ), 9 β ‐hydroxy‐ageraphorone ( 5 ), 10 Hα ‐9‐oxo‐ageraphorone ( 6 ), 10 Hβ ‐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, 1 H and 13 C NMR, EIMS, HMBC and single‐crystal X‐ray spectral data.
