title: Alkaloids from Lupinus argenteus var. stenophyllus.
abstract: TLC and GLC of an alkaloid extract of the aboveground portions of Lupinus argenteus Pursh. var. stenophyllus (Rydb.) Davis (Leguminosae) suggested the presence of sparteine, beta-isosparteine, delta5-dehydrolupanine, alpha-isolupanine, lupanine, thermopsine, and anagyrine. GLC-mass spectrometry confirmed these preliminary findings. Preparative TLC was used to isolate sparteine, and this alkaloid was further characterized by IR spectral analysis and derivatization.
