Halostachine

Alkaloid

Halostachine is a natural product, an alkaloid first isolated from the Asian shrub Halostachys caspica, and structurally a β-hydroxy-phenethylamine related to its better-known "parent" biogenic amine, phenylethanolamine, to the adrenergic drug synephrine, and to the alkaloid ephedrine. The pharmacological properties of halostachine have some similarity to those of these structurally-related compounds, and Halostachys caspica extracts have been included as a constituent of certain OTC dietary supplements, but halostachine has never been developed as a prescription drug. Although it is found in nature as a single stereoisomer, halostachine is more commonly available as a synthetic product in the form of its racemate. In appearance it is a colorless solid.
