Syringaresinol

Syringaresinol is a lignan found in Castela emoryi, in Prunus mume or in Magnolia thailandica.

This compound inhibits Helicobacter pylori motility.

Eleutheroside E, one of the glycosides isolated from the prickly eleutherococcus, is identical with acanthoside D, which is one of the glycosides isolated from the cluster-flowering acanthopanax and represents the di-β-D-glucoside of (−)-syringaresinol.
