Synapine, whose brute or molecular formula is: C16H24NO5, is an alkaloid found in the seeds of some species of plants belonging to the Brassicaceae family.
The discovery of the synapine is due to the French chemist Etienne-Ossian Henry (1798–1873) who identified it in 1825.
Chemically synapine is an ester of choline with synapic acid, which can be found in the simple form in the seeds of black mustard (Brassica nigra (L.) WDJ Koch, 1833) or of Indian mustard (Brassica juncea L. Czern.) Or , in the chemical form of glucosinolate (which is sinalbine) in the seeds of white mustard (Sinapis alba L.).

The synapine has the following properties. It is a white substance, very voluminous and light, with a taste that is first bitter and then recalls that of mustard.
It is soluble in water and in alcohol, coloring them with yellow; the solubility is higher at a higher temperature and crystallizes from the cooling of the hot saturated solution.
