Anthoceros agrestis, commonly called Field Hornwort, is a bryophyte of the Anthoceros genus. It has complicated taxonomies.
This species of anthoceros is known for having enzymes like cinnamic acid 4-hydroxylase (EC 188.8.131.52), a cytochrome P450-dependent hydroxylase. Cinnamic acid 4-hydroxylase (C4H; EC 184.108.40.206) is one of the first known plant cytochrome P450 monooxygenases and also one of the best-characterized cytochrome P450 hydroxylases from higher plants.
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.
