Fifteen compounds were obtained from the twigs and leaves of Caesalpinia minax. Their structures were identified as apigenin (1), 5,7,3',4'- tetrahydroxy-3-methoxyflavone (2), luteolin-5, 3 '-dimethyl-ether (3), thevetiaflavon (4), apigenin-7-O-beta-D-glucuronide (5), bonducellin (6), 7-hydroxy-3-(
Five new neocaesalpins, named neocaesalpin J-N (1-5, resp.), along with the known neocaesalpin A and eight known furanditerpenoids, namely epsilon-caesalpin, 7-acetoxy-epsilon-caesalpin, 14-deoxy-epsilon-caesalpin, caesalmins D-F, and bonducellins C and D, were isolated from the seeds of Caesalpinia
