| Abstract: | A new alkaloid, phlegmariuine-N, was isolated from Phlegmariurus fordii (Baker) Ching. In the present work, a technique of long-range 1H-1H and 13C-1H COSY in combination with NOE difference spectroscopy has been successfully used to connect the spin systems separated by quatermary carbons and heteroatom. Its structure has been elucidated as (I). |
