Isolation, identification and quantitation of hydroxycinnamic acid conjugates, potential platform chemicals, in the leaves and stems of Miscanthus × giganteus using LC-ESI-MSn

► Miscanthus × giganteus is an important source of biofuel and platform chemicals. ► LC-ESI-MSn was used to identify hydroxycinnamic acid conjugates in leaf and stem. ► Twenty-four hydroxycinnamates were identified in leaf, including caffeoylquinic acids. ► Twenty-six compounds were identified in stem, including mandelonitriles and mandelamides.
