Four compounds were isolated from the dichloromethane extract of stem bark of Illicium difengpi by using various column chromatographic methods. Their structures were identified as difengpienol D (1), (E)-3,4-methylenedioxophenyl propenal (2), dihydrocubebin (3) and pestalotiopyrone G (4) respectively by mass spectrometry (MS), infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR), etc. and quantum chemical calculation method. Compound 1 was an unusual new compound formed by acyclic monoterpenoid and phenylpropanoid through C—C chain, and was also the first monoterpene-phenylpropanoid isolated from the genus Illicium. It showed weak anti-inflammatory activity.

Key words: Illicium difengpi, monoterpene-phenylpropanoid, structural identification, absolute configuration
