NMR Application in Selective Separation for Natural Products and Their Structural Investigation
NMR在天然产物选择性分离与结构研究中的应用

NMR has played an important role in Natural Product Chemistry. In this work, NMR technique was used as a valid monitor in the separation process of natural products, in addition to its application in the structural elucidation of natural compounds. In the selective separation of diterpenoid-like compounds from the natural plants, 1H NMR was performed in time after each step of the separation. Combining with the knowledge about the spectral characteristics of the target compounds, the information obtained from 1H NMR spectra was well used to handle the separation work.
