Two new alkaloids, ranaconidine (=20‐ethyl‐1 α ,14 α ,16 β ‐trimethoxyaconitane‐4,7,8,10‐tetrol; 1 ) and N ‐(chloromethyl)taspine (=1‐[2‐( N ‐(chloromethyl)‐ N , N ‐dimethylaminium)ethyl]‐3,8‐dimethoxybenzopyrano[5,4,3‐ cde ]benzopyran‐5,10‐dione; 2 ), together with two known compounds, i.e. , benzethonium chloride ( 3 ) and ranaconine ( 4 ) were isolated from the roots of Aconitum sinomontanum Nakai . The structures of the compounds were elucidated on the basis of spectral evidences and in the comparison with previously published data.
