Anthoceros agrestis, commonly called field hornwort,[4] is a bryophyte of the genus Anthoceros. It has complicated taxonomies.

Taxonomy

This species of Anthoceros is known for having enzymes like cinnamic acid 4-hydroxylase (EC 1.14.13.11), a cytochrome P450-dependent hydroxylase. Cinnamic acid 4-hydroxylase (C4H; EC 1.14.13.11) is one of the first known plant cytochrome P450 monooxygenases[5] and also one of the best-characterized cytochrome P450 hydroxylases from higher plants.[6][7]

Chemistry

Production of Rosmarinic acid and a rosmarinic acid 3'-O-beta-D-glucoside in suspension cultures of this hornwort was also discovered in 2005.[8]

Anthocerodiazonin, an alkaloid, was isolated from in vitro cultures of the species. Also, six glutamic acid amides, N-(4-hydroxybenzoyl)-glutamic acid, N-(3,4-dihydroxybenzoyl)-glutamic acid, N-(4-hydroxy-3-methoxybenzoyl)-glutamic acid, (E)-N-(isoferuloyl)-glutamic acid, (Z)-N-(isoferuloyl)-glutamic acid and (Z)-N-(p-coumaroyl)-glutamic acid were obtained as natural products.[9]
