Iridin is a glucoside of irigenin.

Occurrence

Iris flower ( Iris germanica )

Iridin and its aglycon irigenin belong to the isoflavones and occur together in the roots of iris species ( Iris florentina , Iris germanica , Iris pallida ) and in Belamcanda chinensis .

Chemistry and properties

Iridine forms fine, white needles that melt at 208 ° C and dissolve well in water and ethanol. It is chemically a glycoside with the isoflavone derivative irigenin as an aglycon, to which glucose is O -glycosidically bound. The name iridin must not be confused with the natural product group of iridoids , as their biosynthesis is different.

Other names

A soft resin from the alcoholic extract of Iris versicolor and a protamine from the sperm of rainbow trout are also referred to as iridin .
