摘要：

The labile sesquiterpene hydrocarbon germacrene C is the main constituent of a chemotype of the liverworth Preissia quadrata collected in Southern Germany. Its temperature dependent rearrangement to racemic delta-elemene is observed by capillary gas chromatography using cyclodextrins as chiral stationary phases. In addition, the rarely found ent-sesquiterpenes (+)-germacrene D, (+)-trans-beta-caryophyllene, (+)-beta-caryophylleneoxide, (+)-cubebol and racemic alismol [1 beta,5 alpha-guaia-6,10(15)-dien-4-ol] were identified as major constituents using spectroscopic methods and enantioselective gas chromatography. Minor constituents are (+)-alpha-copaene, (+)-delta-selinene, (-)-delta-cadinene, germacrene B and (-)-cascarilladiene (eudesma-5,7-diene). Copyright (C) 1996 Elsevier Science Ltd
