【摘要】 随着核磁共振技术的发展和设备的普及,核磁共振技术在该天然产物化学研究活动中扮演了越来越重要的角色。本工作利用核磁共振提供的信息指导从狼毒大戟中有针对性提取二萜类化合物的分离工作,收到良好的效果。并在化合物核磁共振结构解析过程中,根据天然产物中化合物成有呈系列化出现的特点有效地组合实验,使核磁共振实验手段多样化的技术优势得以发挥。更多还原

【Abstract】 NMR has been playing an important role in natural product chemical research along with its rapid development and wide application.Here,an NMR technique was used as a monitoring skill in the selective isolation of diterpene compounds from Euphorbia Fischeriana Steud and effective result was obtained.Taking the advantage of the multi-skills available on a modern NMR instrument,the NMR experiments were selected and organized reasonably in the structure analysis for new isolated com- pounds,considering that series of compounds with the similar framework would appear in the same sample of organism.The re- liable NMR information was provided in this way.更多还原
