Infobox references

Vitexin is an apigenin flavone glucoside, a chemical coupound found in the passion flower, Vitex agnus-castus (chaste tree or chasteberry) and in the Phyllostachys nigra bamboo leaves.[1] It is also found in the pearl millet (Pennisetum millet).[2]

Metabolism

Goitrogenicity of millet flavones : Vitexin inhibits thyroid peroxidase thus contributing to goiter.[3][4]

Isovitexin

Isovitexin (or homovitexin, saponaretin) is the apigenin-6-C-glucoside. It can be found in the passion flower and the açaí palm.
