Investigation on the alkaloids of roots of A. albo-violaeeum, collected from Fu-song County, Jilin Province in China, has been led to the isolation of nine C19 diterpenoid alkaloids. Four of them are novel natural constituents and named alboviolaconitine A (I), alboviolaconitine B (II), alboviolaconitine C (III) and alboviolaconitine D(IV). Others were septentriodine, lycaconitine, avadharidine, ammonium puberaconitine, and lycoctonine.
