A novel skeleton alkaloid, excentricine, was isolated from the roots of stephaniaexcentrica. The recent introduced selective long-range DEPT and 1D multiple relay COSY NMR techniques have been successfully used to identify and to connect spin systems separated by quaternary carbons and heterotoms and total assignment of 1H and 13C NMR spectra were achived. Its structure has been elucidated as 1.
