White mustard seed

Sinapine, CjgHjjOgN, was isolated as a thiocyanate from black mustard seeds (Brassica nigra) by Henry and Garot." Will and Laubenheimer first noted that sinapine occurs in white mustard seed in the form of the alkaloidal glucoside sinalbine, CajH jOuNgSg, which, on hydrolysis by the enzyme myrosin, also present in the seed, furnished dextrose, p-hydroxybenzylthiocarbimide and sinapine sulphate. Owing to its instability sinapine is unknown in the free state. The thiocyanate can be recrystallised from water and converted into the acid sulphate by treatment with sulphuric acid. 

Teel Oil, or Oil of Sesamum.—The plant yielding this oil, the sesamum orientals, is extensively cultivated throughout India for the sake of the fine oil expressed from its seeds. The latter are imported from Calcutta under the name of teel seeds. They are about the size of white mustard seeds. Three varieties are known— namely, the white, the particolored, and the block. It is principally from the latter that the eesumum oil of commerce is obtained. The seed contains about forty-five per cent, of oil. This has been already mentioned as an adulterant of almond oil, and, according to Pereira, may be used as a substitute for the latter.

An example of important non-volatile nitriles is 4-hydroxybenzyl cyanide, which is found in mustard pastes made from white mustard seeds Leucosinapis album) containing glucosinolate sinalbin. Nonvolatile nitriles also include cyanogenic glycosides, cyanogenic lipids and amino acids that contain the cyano group. 

White mustard seeds, from Brassica alba, contain the glucoside sinalbin, CggH NoS Oj, which on decomposition in the same manner as the glucoside of black mustard yields glucose, sinapine sulphate, and the evil-smelling oil, acrimyl-thiocarbimide (p-hydroxy-benzyl-iso-thiocy-anate). The reaction takes place as follows —...
