Three novel and one known hydroxycinnamic acid amides were isolated from pollen of Quercus dentata Thunb. They were identified as N-1,N-5,N-10-tricaffeoylspermidine, N-1-p-coumaroyl-N-5,N-10-dicaffeoylspermidine, N-1,N-10-di-p-coumaroyl-N-5-caffeoylspermidine and N-1,N-5,N-10-tri-p-coumaroylspermidine, respectively. Information on the position of the hydroxycinnamoyl moieties was derived from electrospray mass spectral fragmentation patterns.
