【摘要】 核磁共振(NMR)是天然产物化学研究的重要手段.本工作将核磁共振技术作为选择性提取分离的监测手段,依据目标化合物的NMR谱学特征,以1H NMR监控和指导从植物体中寻找和得到二萜类化合物收到了较好的效果.并运用多种核磁共振技术对分离得到的3种二萜类化合物(jolkinolide A、jolkinolide B和17-hydro-xyjolkinolide B)进行了结构解析.更多还原

【Abstract】 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.更多还原
