摘要：

A new polyisoprenylated benzophenone, guttiferone 1, together with the known compounds cambogin, 1,7-dihydroxyxanthone, 1,3,6,7-tetrahydroxyxanthone and 1,3,5,6-tetrahydroxyxanthone were isolated from the stern bark of Garcinia griffithii. The acetone extract of the heartwood of Garcinia mangostana contained one new diprenylated xanthone (mangoxanthone) and a new benzopttenone (3',6-dihydroxy-2,4,4'-trimethoxybenzophenotie) as well as the known xanthones dulxanthone D, 1,3,7-trihydroxy-2-methoxyxanthone, 1,3,5-trihydroxy-13,13-dimethyl-2H-pyran[7,6-b]xanthen-9-one. Their structures were established oil the basis of spectroscopic studies and chemical correlation. (c) 2005 Elsevier Ltd. All rights reserved.
