A new cassane furanoditerpene, 17‐methylvouacapane‐8(14),‐9(11)‐diene (1), has been isolated from the seed kernels of Caesalpinia crista and its structure determined by mass, IR and NMR spectrometry. The 1 H‐ and 13 C‐NMR spectra were assigned using a combination of 1 H‐ 1 H COSY, HSQC and HMBC two‐dimensional NMR experiments. An HPTLC method has been developed to quantify 1 in seed material. The furanoditerpene can serve as a marker chemically to differentiate C. crista from the synonymous C. bonduc . Copyright © 2003 John Wiley & Sons, Ltd.
