摘要

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.
