A Senecio alkaloid also present in S. Jacobea, this base has [α] D - 140° (CHC13)
and is hydrolyzed to retronecine and jacozinecic acid. The base contains a
methylene group and the ultraviolet spectrum has a single absorption maximum
at 233 mμ.
ChEBI: Jacozine is a pyrrolizine alkaloid that is seneciphylline in which the exocyclic double bond has been converted to the corresponding epoxide. It has a role as a Jacobaea metabolite. It is a macrocyclic lactone, an organic heterotricyclic compound, a pyrrolizine alkaloid, a spiro-epoxide, a tertiary alcohol and a tertiary amino compound. It is functionally related to a seneciphylline.
