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
