Abstract

Two new lupin alkaloids, (+)-14-dehydro-10a-hydroxytermisine, (-)-13a-hydroxy-5,6-dehydromultiflorine N-oxide have been isolated from the ethanolic extract of Lupinus albus seeds together with (+)-13a-(2-methylbutyryl)-oxylupanine, (+)-a-isolupanine, (+)-ammodendrine and (-)-sparteine. The structure elucidation of these alkaloids is based on spectroscopic and semisynthetic methods.
