本文结合国内外文献,总结了作者从美丽獐牙菜中获得的酮类化合物的结构特征及其UV、IR、NMR、MS波谱学规律。着重分析了酮的NMR数据,总结出了依据羟基和羰基的δ值确定其取代类型,跟据糖端基质子的化学位移值及耦合常数来判断连接位置和构型的核磁共振波谱规律。为今后进一步分析鉴定酮类化合物结构及进行波谱数据的归属提供理论基础。 In this paper, combined with domestic and foreign literature, the author summarizes the structural characteristics of the fenvalerate compounds obtained from the beautiful Swertia japonica and its UV, IR, NMR, MS spectroscopy. The NMR data of chironinone were mainly analyzed, and the substitution types were determined based on the δ values ​​of hydroxyl and carbonyl groups. The NMR spectra of the linker and its configuration were determined according to the chemical shifts and the coupling constants of the proton of the sugar end. It provides the theoretical basis for further analysis and identification of chorion compounds and the assignment of spectral data.
