5. Glucosinolates or thioglycosides:

Definition:
       The aglycones of this group of glycosides contain sulphur and

sometimes called thiocyanate or sulphurated glycosides.

A number of plants of the family Cruciferae yield glucosinolates e.g.

Brassica nigra (black mustard) yields sinigrin glycoside.

Brassica alba (white mustard) yields sinalbin glycoside.
