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.^{[citation needed]}

Metabolism

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