Anthoceros agrestis, commonly called Field Hornwort, is a bryophyte of the Anthoceros genus. It has complicated taxonomies.

Taxonomy[edit]

A specimen of anthoceros agrestis in Schwäbisch-Fränkische Waldberge, Deutschland.

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[4] and also one of the best-characterized cytochrome P450 hydroxylases from higher plants.[5][6]

Chemistry[edit]

Production of rosmarinic acid and a rosmarinic acid 3'-O-beta-D-glucoside in suspension cultures of this hornwort was also discovered in 2005.[7]

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.[8]
