摘要： 从湖北蟹甲草根茎中分得一个新的生物碱,选择性远程DEPT ¹³C NMR新技术用于识别NMR信号归属和连接被季碳及杂原子分割的质子自旋系统,确定其结构为新阔叶千里光碱的氮氧化物,如(1)所示。

关键词: 选择性远程DEPT ¹³C NMR, 新阔叶千里光碱的氮氧化物

Abstract: A new alkaloid, neuplatyphyllinc N-oxide, was isolated from the root of Caculia hupehensis Hand-Mazzi. Selective long-range DEPT ¹³C NMR new technique has been sucessfully used to identify ¹³C nuclei and to connect the spin system separated by quaternary carbons and heteroatoms in the compound. Total assignment of ¹H and ¹³C NMR spectra of the compound were achieved. Its structure has been elucidated as (1).

Key words: Selective long-range DEPT ¹³C NMR, Neuplatyphylline N-oxide
