This alkaloid, which has been isolated from the leaves of Cadaba fruticosa, has been shown, by comparison of its hydrochloride and the NMR spectrum, to be stachydrine.

Stachydrine is used for various ethnobotany and ethnomedicinal uses. It can also be used to promote healthy neural development in an unborn baby, as well as to determine the differential effects of post-weaning diet and maternal obesity on mouse liver and brain metabolomes.

ChEBI: L-proline betaine is an amino acid betaine that is L-proline zwitterion in which both of the hydrogens attached to the nitrogen are replaced by methyl groups. It has a role as a food component, a plant metabolite and a human blood serum metabolite. It is a N-methyl-L-alpha-amino acid, an alkaloid and an amino-acid betaine. It is functionally related to a L-prolinium. It is a conjugate base of a N,N-dimethyl-L-prolinium. It is an enantiomer of a D-proline betaine.
