Abstract

Nine new alkaloids przewaline, przewalskine, przewalskinine, przewalstine, przewalstinine, przewalstidine, przewalstidinine, przewalidine chloride, and 8-hydroxypseudocoptisine chloride were isolated from Thalictrum przewalskii Maxim., together with the known alkaloids berberinium chloride, magnoflorine chloride, N-methylpalaudinium chloride, thalphenine chloride, and N-methylnantenium chloride. Their structures were determined by spectroscopy including EI-MS, FAB-MS, ¹H-NMR, ¹³C-NMR, C,H-COSY, C,H-COLOC, HMQC and HMBC techniques.

Key words

Thalictrum przewalskii - Ranunculaceae - aporphine-benzylisoquinoline dimers - aporphine alkaloids - protoberberine alkaloids - isopavine alkaloids
