摘要：

Four new cassane type furanoditerpenoids (1-4) were isolated from the air dried leaves of Caesalpinia pulcherrima Their structures were elucidated by spectral data interpretation The exocyclic methylene compound 1 readily isomerized and oxidized to the benzofuran 4 Benzyl 2,6 dimethoxybenzoate (5) was also identified in this study Antimicrobial tests on 1-5 indicated that they were active against several bacteria (S aureus, E colt, P aeruginosa, and B subtilis) and fungi (C albicans and T mentagrophytes).
