采用多种柱色谱分离技术对地枫皮树皮进行深入的化学成分研究, 从其二氯甲烷部位中分离得到4个化合物, 并通过质谱(MS)、红外光谱(IR)、核磁共振光谱(NMR)等谱学技术和量子化学计算方法对其结构分别鉴定为地枫皮醇D (1)、(E)-3,4-亚甲二氧基苯丙烯醛(2)、二氢荜澄茄素(3)和pestalotiopyrone G (4). 化合物1是一个罕见的由链状单萜与苯丙素通过C—C杂合的新化合物, 为八角属植物中首个单萜杂合苯丙素类成分. 化合物1显示出弱的抗炎活性.

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
