摘要：

SESQUITERFENES FROM THE SEEDS OF Guarea guidonia (MELIACEAE). Two new sesquiterpenes 6 alpha-ethoxyeudesm 15)-en-1 beta-ol (1) and (7R*)-5-epi-opposit-4(15)-ene-1 beta,7-diol (6), were isolated from the seeds of a specimen of Guarea guidonia (Meliaceae). Five other known sesquiterpenes, eudesm-4(15)-ene-1 beta,6 alpha-diol (2), 5-epi-euclesm-4(15)-ene-1 beta,6 beta-diol (3), eudesm-4(15)-ene-1 beta,5 alpha-diol (4), eudesm-4(15),7-dien-1 beta-ol (5) and (7R*)-opposit-4(15)-ene-1 beta,7-diol (6), were also isolated in this work. Their structures were determined on the basis of spectral data (MS. IR. and NMR-1D and 2D) and subsequent comparisons with the literature. The substances 3, 4 and 6 are reported for the first time in Meliaceae and 5 for the first time in the genus Guarea.
