Mass spectrometry of prieureanin limonoids

The electron impact mass spectral fragmentation patterns for six closely related limonoids, namely, hispidins A, B and C (rohituka 7), prieureanin, dregeanin and rohitukin, with the aid of high resolution exact mass measurement and metastable study, are described and interpreted.
