Abstract: A new cassane diterpene, neocaesalpin W (1), along with a known triterpene, β-amyrin (2) was isolated from the seeds of Caesalpinia bonduc (fabaceae). The structure and relative stereochemistry of (1) was determined by spectral methods (1H NMR, 13C NMR, H-HCOSY, HMBC, HMQC and NOESY experiments. ESI-MS, IR).
