Four novel polyisoprenylated benzophenone derivatives, paucinones A-D (1-4), were isolated from the leaves of the plant Garcinia paucinervis. Paucinones A-C (1-3) contained an unexpected cyclohexane-spiro-tetrahydrofuran moiety. A 1-methylene-3,3-dimethylcyclohexane group never reported before was found in the structure of paucinone D (4). The structures of these compounds were elucidated with spectroscopic evidences. The relative stereochemistries of 1-4 were determined by NOESY correlations. These compounds showed significant cytotoxicities against HeLa cells. © 2010 Elsevier Ltd. All rights reserved.
