title: Alkaloids from Thalictrum przewalskii.
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, (1)H-NMR, (13)C-NMR, C,H-COSY, C,H-COLOC, HMQC and HMBC techniques.
