| Abstract: | The stem bark of Garcinia quadrifaria has yielded the novel xanthone 1, 3, 5-trihydroxy-4, 8-di(3,3-dimethylallyl)xanthone and the biflavonoids O-methylfukugetin and morelloflavone. The seeds contained the biflavonoids but not the xanthone. G. staudtii stem bark gave rheediaxanthone-A and the polyisoprenylated benzophenone xanthochymol. . |
