Analysis of sparteines in the seeds of

Abstract

Seven alkaloids were isolated from the seeds of Ammopiptanthus mongolica by thin layer chromatography and silica gel column chromatography, and the chemical structures of five alkaloids, 17-oxosparteine, ?-isosparteine, 3?-hydroxysparteine, sparteine, and 3?-hydroxysparteine were identified by ¹H nuclear magnetic resonance (NMR) and electron ionization mass spectrum (EIMS).
