Abstract Three novel and one known hydroxycinnamic acid amides were isolated from pollen of Quercus dentata Thunb. They were identified as N1,N5,N10-tricaffeoylspermidine, N1-p-coumaroyl-N5,N10-dicaffeoylspermidine, N1, N10-di-p-coumaroyl-N5-caffeoylspermidine and N1, N5, N10-tri-p-coumaroylspermidine, respectively. Information on the position of the hydroxycinnamoyl moieties was derived from electrospray mass spectral fragmentation patterns.

来自齿科栎花粉的三取代羟基肉桂酸亚精胺

摘要 从Quercus dentata Thunb 花粉中分离得到3 种新型羟基肉桂酰胺和1 种已知羟基肉桂酰胺。它们被鉴定为 N1,N5,N10-三咖啡酰亚精胺、N1-对香豆酰-N5、N10-二咖啡酰亚精胺、N1、N10-二-对-香豆酰-N5-咖啡酰亚精胺和 N1、N5、N10-三-对香豆酰亚精胺分别。羟基肉桂酰基部分的位置信息来自电喷雾质谱碎片模式。
