From the ethanolic extract of Caesalpinia bonduc, one new diterpene, neocaesalpin P (1) and six known diterpenoids, neocaesalpin H (2), cordylane A (3), caesalpinin B (4), bonducellpin E (5), caesalpinolide A (6), and 17-methylvouacapane-8(14),-9(11)-diene (7) were isolated. Structures of these compounds were determined from NMR spectroscopic studies. Compounds 1-7 exhibited modest antibacterial activities. All of these compounds were weakly active in glutathione S-transferase inhibition assays.
