In this work the use of basic nonaqueous conditions is suggested as a general method for the extraction of quinolizidine alkaloids. The extraction of quinolizidine alkaloids from fresh flowers of Spartium junceum is performed in ethanolic basic conditions. The procedure is efficient and selective. The extract is essentially formed by N-formylcytisine, N-methylcytisine, cytisine and anagyrine. The method allows a high recovery of N-formylcytisine which becomes the predominant alkaloid in S. Junceum flowers.

Abstract
In this work the use of basic nonaqueous conditions is suggested as a general method for the extraction of quinolizidine alkaloids. The extraction of quinolizidine alkaloids from fresh flowers of Spartium junceum is performed in ethanolic basic conditions. The procedure is efficient and selective. The extract is essentially formed by N-formylcytisine, N-methylcytisine, cytisine and anagyrine. The method allows a high recovery of N-formylcytisine which becomes the predominant alkaloid in S. Junceum flowers.File in questo prodotto:
