摘要
Phytochemical investigation on the seeds of Caesalpinia decapetala led to the isolation of a new cassane diterpenoid with an unusual O bridge between C-19 and C-20, named phanginin Q (1), together with three known cassane diterpenoids, caesaljapin (2), caesaldekarin A (3), and caesaldekarin B (4). The structure of the new compound was elucidated by spectroscopic methods, including H-1 NMR, C-13 NMR, HSQC, H-1-H-1 COSY, HMBC, NOESY, and HR-ESI-MS.
