Trisubstituted hydroxycinnamic acid spermidines from Quercus dentata pollen

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-coumar...

Description
Summary: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.
