Russian comfrey (Symphytum x uplandicum Nyman) is widely recommended as a medicinal herb and an item of human diet. A previous investigation of this species led to the isolation of three alkaloids which were not fully characterized (cf. Vol. 7, p. 57). Culvenor and co-workers have separated eight pyrrolizidine alkaloids from the leaves of this perennial plant by counter-current distribution.21 The known alkaloids echimidine (51), symphytine (52), lycopsamine (53), and intermedine (54) were present. In addition, four new alkaloids, i.e. 7-acetyl-lycopsamine (55), 7-acetylintermedine (56), symlandine (57), and uplandicine (58), were characterized by spectroscopic methods, and by hydrolysis. The total alkaloidal extract caused chronic hepatotoxic effects in rats, and the authors... [Pg.51]
