The alkaloids hitherto found in Thalictrum minus L. ssp. maju (known also as Thalictrum minus ssp. datum in some earlier papers) belong mainly to the aporphine-benzylisoquinoline group (1-5). Here we report the isolation of two known alkaloids, namely, thalicthuberine (6,7) and thaliadine (€9, as minor alkaloids from the roots of T. minus ssp. majus.
