A novel cassane-type furanoditerpenoid lactone, named macrocaesalmin, possessing a ten-membered macrocyclic 1,5-diketone ring and an unprecedented cis B/D ring fusion mode, has been isolated from the seeds of Caesalpinia minax Hance. Its structure was elucidated from detailed 1D and 2D NMR spectral
## Abstract A new dimer **1** and two new cassaneβtype diterpenes **2** and **3**, designated taepeenin JβL, were isolated from the seeds of __Caesalpinia crista__ L. Compound **1** possesses a dimeric vouacapane skeleton. Their structures were elucidated on the basis of spectroscopic analysis.
## Abstract Two novel cassaneβtype diterpenes, named magnicaesalpin (**1**) and neocaesalpin O (**2**), together with three known compounds, caesalmin D (**3**), caesalmin E (**4**), and neocaesalpin L (**5**), were isolated from the MeOH extract of seeds of __Caesalpinia magnifoliolata__ Metc. The
