Five new cassane‐type diterpenes, caesalpinista A ( 1 ), caesalpinista B ( 2 ), caesaljapin B ( 3 ), caesaljapin C ( 4 ), and caesalpinilinn ( 5 ) were isolated from the MeOH extract of the seeds of Caesalpinia crista. Their structures were elucidated by the analysis of their 1D‐ and 2D‐NMR spectra.
