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.

It can be found in the passion flower, Cannabis, oat and the açaí palm.^[1]

• Isovitexin beta-glucosyltransferase

Saponarin is the isovitexin-7-O-glucoside.

• Vitexin, the 8-C-glucoside of apigenin
• Isoorientin, the 3'-OH derivative
