A new hydroxycinnamoyl polyamine derivative, N,N′,N″-triferuloylspermidine (= (E)-N-(4-aminobutyI)-3,3′,3″-tris(4-hydroxy-3-methoxyphenyl)-N,N′,N″-(butane-1,4-diyl)tris [prop-2-enamide]) (1) was detected in the H2O /MeOH extract of pollen from Hippeastrum × hortorum. The compound was identified by on-line-coupled high-performance liquid chromatography and atmospheric-pressure chemical-ionization mass spectrometry (HPLC-UV(DAD)/ APCI-MS and MS/MS). The structure was proven by comparing the HPLC/MS data after UV-induced (E) ⇄ (Z) photoisomerization and catalytic hydrogenation of the natural compound and the synthetic reference compound. This is the first report of a triferuloylspermidine in nature
