Abstract
The alkaloidal extract from L. pilosus was found to contain two alkaloids, one widely occurring one, d-lupanine, and one which had already been reported to occur in this plant, i.e., d-epilupinine, but no lupinine. The alkaloid tetralupine has been found to be identical with dl-epilupinine. A study of the infrared absorption spectra of lupinine and epilupinine leads to the same conclusion as the chemical evidence, i.e., that in the former the hydroxymethylene group occupies the axial position whereas in epilupinine this group is in the equatorial position.This publication has 1 reference indexed in Scilit:
