The Alkaloids of Thalictrum foliolosum

Abstract

A defatted ethanolic extract of the roots of Thalictrum foliolosum DC. (Ranunculaceae) afforded the alkaloids thalrugosidine (1), thalrugosaminine (2), thalisopine (thaligosine) (3), thalirugidine (4), oxyberberine (berlambine) (5), and noroxyhydrastinine (6) after the usual systematic partitioning and chromatographic procedures.'To whom inquiries should be directed.

8-Hydroxydihydrochelerythrine and 8-Hydroxydihydrosanguinarine with a Potent Acetylcholinesterase Inhibitory Activity from Chelidonium majus L.

“…Compounds 1-4 were identified to be 8-hydroxydihydrochelerythrine, 14) 8-hydroxydihydrosanguinarine, 15) noroxyhydrastinine, 16) and berberine, 17) respectively, which mass and NMR spectral data Vol. 29, No.…”
