Vitexin is an apigenin flavone glucoside, a chemical compound found in the passion flower, Vitex agnus-castus (chaste tree or chasteberry), in the Phyllostachys nigra bamboo leaves,[1] in the pearl millet (Pennisetum millet),[2] and in Hawthorn.[3]
Metabolism
Goitrogenicity of millet flavones : Vitexin inhibits thyroid peroxidase thus contributing to goiter.[4][5]
