Simultaneous identification and analysis of cassane diterpenoids inCaesalpinia minaxHance by high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry

Cassane diterpenoids were successfully and simultaneously identified in Caesalpinia minax Hance by high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry. A total of 59 peaks were detected, and among them 51 compounds, including 41 furanocassane diterpenoids, 10 furanolactone cassane diterpenoids were simultaneously identified and characterized on the basis of the protonated molecule, retention...
