A new spermidine triamide derivative has been isolated from peanut flowers and identified as N (1)-acetyl- N (5), N (10)-di- p-( EE)-coumaroylspermidine on the basis of detailed analysis of NMR, MS, and UV data. Two other spermidine conjugates, N (1), N (5), N (10)-tri- p-( EEE)-coumaroylspermidine and di- p-( EE)-coumaroylspermidine, as well as four flavonoid conjugates (quercetin-3-glucoside, quercetin-3-glucuronide, isorhamnetin-3-glucoside, and isorhamnetin-3-glucuronide) that have been previously reported in organs of other plants, have been found in this study in peanut ( Arachis hypogaea L.), a representative of the Leguminosae family, for the first time. The dynamics of photoisomerization in the spermidine conjugates have been investigated.
从花生花中分离出一种新的亚精胺三酰胺衍生物,基于对核磁共振、质谱和紫外数据的详细分析,鉴定为N(1)-乙酰基-N(5),N(10)-二对-(EE)-香豆酰亚精胺。另外两种亚精胺共轭物,N(1),N(5),N(10)-三对-(EEE)-香豆酰亚精胺和二对-(EE)-香豆酰亚精胺,以及四种先前已在其他植物器官中报道过的黄酮共轭物(槲皮素-3-葡萄糖苷、槲皮素-3-葡萄糖醛酸苷、异鼠李素-3-葡萄糖苷和异鼠李素-3-葡萄糖醛酸苷),在本研究中首次在豆科植物代表花生(Arachis hypogaea L.)中被发现。对亚精胺共轭物中的光异构化动力学进行了研究。
