Acylated flavonol tri- and tetraglycosides in the flavonoid metabolome of Cladrastis kentukea (Leguminosae)

► Leaves of Cladrastis kentukea contain a complex mixture of acylated flavonoids. ► Twelve unreported acylated flavonol glycosides from Cladrastis are characterised by NMR. ► The acylated glycan of Cladrastis flavonoids has not been widely reported. ► Presence of acylated flavonol glycosides distinguishes Cladrastis from Styphnolobium.
