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[edit]

Goitrogenicity of millet flavones : Vitexin inhibits thyroid peroxidase thus contributing to goiter.[4][5]

  • Isovitexin (or homovitexin, saponaretin) is the apigenin-6-C-glucoside.
  • Orientin, the 3'-OH derivative

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
