Abstract

A mass spectrometry method that combines electrospray with an ion trap time-of-flight mass analyzer has been used to characterize puerarin (7,4'-dihydroxyisoflavone-8-C-beta-D-glucoside). MS' spectra (n <= 6) were obtained in positive and negative ion mode. The combination of accurate mass measurement in MS2 spectra and sequential MSn experiments enabled fragmentation pathways to be elucidated in detail. A novel structure for [M+H-150]+ has been found.
