Description
An a-naphthaphenanthridine alkaloid, this base occurs in the roots of Sanguinaria
canadensis. It is separated from the remaining bases by chromatography and
purified by crystallization from CHC13 followed by sublimation in a high
vacuum. It is optically inactive and may also be prepared by oxidation of
sanguinarine nitrate by potassium ferricyanide in alkaline solution. No salts of
this alkaloid have been prepared.
