Abstract: From the floral resins of Clusia nemorosa male. C. nemorosa hermaphrodite, Clusia rosea female. Clusia grandflora, male, C. grandflora female, Clusia insignis male (all section Chlamydoclusia), C. renggerioides male (with pistillodium). C. renggerioides male (without pistillodium), C. renggerioides female (all section Cordylandra) belonging to the family Clusiaceae. we have isolated two novel polyisoprenylated benzophenones, nemorosone II and 6-epi-nemorosone, and a xanthone. The latter is the first member of this class of compounds ever isolated from the genus Clusia. HPLC allowed the quantification of these and other methylated benzophenones in the methylated resins revealing that indeed these are the major constituents of Clusia floral resins. Oleic, stearic and some unusual long chain esters and acids are the main constituents of the stamen oils. (C) 1999 Elsevier Science Ltd. All rights reserved.
