| symphytine Usage And Synthesis |
Description | 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. | References | Furuya, Araki., Chem. Pharm. Bull. (Tokyo), 16,2512 (1968)
