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] Vitexin is also found in Hawthorn.
Metabolism
Goitrogenicity of millet flavones : Vitexin inhibits thyroid peroxidase thus contributing to goiter.[3][4]
See also
Isovitexin (or homovitexin, saponaretin) is the apigenin-6-C-glucoside.
