Abstract
A new lupin alkaloid, (+)-sparteine N-16-oxide was isolated from Lygos raetam var. sarcocarpa, together with five known alkaloids: (+)-aphylline, (+)-17 oxosparteine, (-)-5,6-dehydrolupanine, (-)-N-formyl cytisine and (+)-ammodenderine. The structure of the new alkaloid including absolute configuration was determined by spectroscopic methods and chemical transformation.
