(—)-HOMOSTACHYDRINE, A NEW ALKALOID ISOLATED FROM THE SEEDS OF MEDICAGO SATIVA L. GRIMM

Abstract
The seeds of Medicago sativa (alfalfa) have previously been shown to contain other bases besides stachydrine. One of these bases has now been isolated and found to be a homologue of stachydrine for which the name homostachydrine is suggested. (—)-Homostachydrine is shown to be identical with the (—)-methyl betaine of pipecolic acid. The synthetic racemate of the betaine of pipecolic acid has similar properties to homostachydrine, and their infrared spectra and X-ray powder diagrams are identical.
