Abstract

In this article we present the correlations observed in the NOESY spectra, which provide direct and unequivocal detection of hydroxyl groups occurring in the chemical structures of three sesquiterpene lactones - a germacranolide (8α-()4'-hydroxysenecioyloxy-9α-hydroxyparthenolide) and two guaianolides (cynaropicrin and desacylcynaropicrin 8α-()-(4'-hydroxy-2'-methyl)butenoate). The NOESY spectra and other NMR spectra, which served for the structural determination, are also presented. The data provided in this article are associated with the research article "Phytochemical profiles of the leaves of and and their chemotaxonomic implications" Nawrot et al., 2019.

摘要

在本文中，我们展示了在NOESY谱中观察到的相关性，这些相关性提供了对三种倍半萜内酯化学结构中存在的羟基的直接且明确的检测——一种吉马烷型内酯（8α-（）4'-羟基千里光酰氧基-9α-羟基小白菊内酯）和两种愈创木烷型内酯（刺菜蓟苦素和去酰基刺菜蓟苦素8α-（）-（4'-羟基-2'-甲基）丁烯酸酯）。还展示了用于结构测定的NOESY谱和其他NMR谱。本文提供的数据与研究论文“ 和叶片的植物化学概况及其化学分类学意义”Nawrot等人，2019年相关。
