Isolation of symlandine from the roots of common comfrey (Symphytum officinale) using countercurrent chromatography

J Nat Prod. 2001 Feb;64(2):251-3. doi: 10.1021/np0004653.

Abstract

Three pyrrolizidine alkaloids, symlandine, symphytine, and echimidine (1-3), were isolated from the roots of Symphytum officinale using a one-step countercurrent chromatography procedure. The structures of 1-3 were confirmed by several spectroscopic techniques including 2D NMR methods. This is the first description of the separation of symlandine (1) from its stereoisomer, symphytine (2).
