Alkaloids from Lupinus argenteus var. stenophyllus.
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.
