Description and Uses

An amorphous alkaloid, leonurine has been obtained from the leaves of Leonurus sibiricus L. and is characterized as the crystalline hydrochloride hydra te, m.p. 19l-4°C. Hydrolysis yields syringic acid and Q-hydroxybutylguanidine. The total synthesis of the alkaloid has been achieved, confirming the above structure.

Leonurine Hydrochloride is an alkaloid plant extract used in the treatment of uterine disorders. Used in the modification of uterine contractions in rats.
