Beschreibung

This pyrrolizidine alkaloid occurs in the roots of Symphytum officinale Linn. and is difficult to crystallize. The above structure has been proposed on the basis of chemical degradation and spectroscopic evidence.

Definition

ChEBI: A but-2-enoate ester obtained by formal condensation of the carboxy group of (2E)-2-methylbut-2-enoic acid with the 1-hydroxy group of (1R,7aR)-7-({[(2S,3S)-2,3-dihydroxy- -isopropylbutanoyl]oxy}methyl)-2,3,5,7a-tetrahydro-1H-pyrrolizin-1-ol.
