Cowabenzophenones A and B, two new tetracyclo[7.3.3.33,11.0 3,7]tetradecane-2,12,14-trione derivatives, from ripe fruits of Garcinia cowa

Two new tetracyclo[7.3.3.3 3,11 .0 3,7 ]tetradecane-2,12, 14-trione derivatives, cowabenzophenones A (1) and B (2), were isolated from ripe fruits of Garcinia cowa Roxb. Their structures were determined by spectroscopic methods. The tetracyclo[7.3.3.3 3,11 .0 3,7 ]tetradecane-2,12,14-trione skeleton...

Description
Summary:Two new tetracyclo[7.3.3.3 3,11 .0 3,7 ]tetradecane-2,12, 14-trione derivatives, cowabenzophenones A (1) and B (2), were isolated from ripe fruits of Garcinia cowa Roxb. Their structures were determined by spectroscopic methods. The tetracyclo[7.3.3.3 3,11 .0 3,7 ]tetradecane-2,12,14-trione skeleton from the Garcinia genus is reported for the first time. © 2013 Elsevier B.V.
