Chemical shift assignments of two oleanane triterpenes from Euonymus hederaceus

1H-NMR and 13C-NMR assignments of 12-oleanene-3,11-dione (compound 1) were completely described for the first time through conventional 1D NMR and 2D shift-correlated NMR experiments using 1H-1HCOSY, HMQC, HMBC techniques. Based on its NMR data, the assignments of 28-hydroxyolean-12-ene-3,11-dione (compound 2) were partially revised.

2D NMR对金钱松皮中的一个三萜皂苷进行结构解析(英文)

通过核磁共振谱并结合文献对一个三萜皂苷dammar-24(25)-ene-3β,6α,12β,20(S)-tetraol-20-O-β-D-pyranoglucoside进行结构解析.通过2D NMR(1H-1H COSY、HMQC、HMBC)对其进行了NMR全归属.

水团花属植物化学成分和药理作用研究进展

目的对水团花属植物的化学成分和药理作用进行系统的综述,为合理的开发利用水团花属植物资源提供科学依据和理论基础。方法查阅水团花属的研究文献,分析、归纳后进行综述。结果目前水团花属植物化学成分、药理作用方面的研究比较深入;临床应用方面的报道较少。结论需要进一步研究水团花属植物化学物质基础和药理作用机制,充分发挥其药用价值。
