Abstract
Thalictrum minus L. populations of the South-East of Bulgaria (Topolov-grad) represent a distinct chemotype.
They contain N-methylcanadine hydroxide as main alkaloid in the herb. The main alkaloid
(I) is accompanied by O-methylthalmethine (II), thalmethine (III), thalicberine (IV),
O-methylthalic-berine (V), berberine (VI), argemonine (VII), eschscholzidine (VIII),
glaucine (IX) and thalipoline. (I) was observed for the first time in Bulgarian plants
belonging to Th. minus. The pavine alkaloids (VII) and (VIII) have been detected for the first time in Th. minus. Thalipoline is assumed to be a new pavine alkaloid.
