Glycosidic alkaloids from Lupinus varius

A new glycosidic alkaloid, (−)-( trans-3′-methoxy-4′- α- l-rhamnosyloxy cinnamoyl)epilupinine, was isolated from the aerial parts of Lupinus varius, together with the eight knownalkaloids, (−)-( trans-4′- α- l-rhamnosyloxycinnamoyl) epilupinine, (+)-( trans-4′-hydroxy-3′-methoxy-cinnamoyl) epilupini...

Description
Summary:A new glycosidic alkaloid, (−)-( trans-3′-methoxy-4′- α- l-rhamnosyloxy cinnamoyl)epilupinine, was isolated from the aerial parts of Lupinus varius, together with the eight knownalkaloids, (−)-( trans-4′- α- l-rhamnosyloxycinnamoyl) epilupinine, (+)-( trans-4′-hydroxy-3′-methoxy-cinnamoyl) epilupinine, (+)-epilupinine, (+)-epilupinine- N-oxide,(−)-multiflorine, (−)- δ 5-dehydromultiflorine, (+)-ammodendrine and (−)-sparteine. Benzoylepilupinine was identified by GC–mass spectral analysis. The structure of the new glycosidicalkaloid was determined by chemical and spectroscopic methods.
