Nine new cassane-type diterpenes, named taepeenin A–I, and two new norcassane-type diterpenes, named nortaepeenin A–B, were isolated from the stems and roots of Caesalpinia crista along with three known diterpenes: vinhaticoic acid, methyl vinhaticoate and ent-11b-hydroxy-rosa-5,15-diene. Their structures were elucidated on the basis of spectroscopic analysis. In addition, the structure of taepeenin A was confirmed by X-ray diffraction analysis.
