Isovitexin (or homovitexin, saponaretin) is a flavone, namely the apigenin-6-C-glucoside. In this case, the prefix 'iso' does not imply an isoflavonoid (the position of the B-ring on the C-ring), but the position of the glucoside on the flavone, in comparison to vitexin.

Natural occurrence

It can be found in the passion flower, Cannabis, oat and the açaí palm.

Metabolism

Glycosides

Saponarin is the isovitexin-7-O-glucoside.
