There are three reported dimeric bensylisoqulnoline-aporphlne alkaloids, thalicarpine (I) (l), thalmelatine (II) (21 and dehydrothalicarpine (III) (31. They have been found almost.excluslvely in the genus Tbalictrum, family Ranunculaceae except for thalicarpine which has also

Reticuline considered as the most possible precursor of thalicarpine has been administered into intact plants of Thalictrum minus and its incorporation established in both benzyliscquinoline andaprthine parts of this alkaloid.
In a previous paper 1) , one of the authors has reported the isolation of a new phenolic alkaloid, to which the tentative name, Base-B, has been given, from Stephania japonica Miers grown in Formosa.\* The present communication
