核磁共振谱测定黄酮类化合物的结构是一个十分快速简便的方法。在黄酮的基本骨架中,由于取代基种类和位置的不同,芳环和杂环上质子各有其特征化学位移和裂分图像。本文对前文中所报道的十三种黄酮进行核磁共振谱测定(表1),证实了这些化合物的结构,并研 Nuclear magnetic resonance spectroscopy to determine the structure of flavonoids is a very quick and easy method. In the basic structure of flavonoids, due to the different types of substituents and their positions, the protons in aromatic and heterocyclic rings have their own characteristic chemical shifts and split images. In this paper, the thirteen flavonoids reported in the previous study were characterized by NMR (Table 1), confirming the structure of these compounds
