Abstract

The fragmentation pathways of two isomers of brassinosteroids, 28-homobrassinolide (28-h-BL) and 28-epihomobrassinolide (28-eh-BL), have been investigated by tandem mass spectrometry (MSn, n = 1, 2, 3, 4) with the electrospray ionization (ESI) source. The ESI mass spectrometric fragmentation pathways of protonated 28-h-BL and 28-eh-BL were comprehensively elucidated, and the principles revealed in this investigation could potentially be used to identify and distinguish brassinosteroids and their isomers.
