From gametophytes of
Mnium hornum have been isolated a sophorotriose caffeate, three biflavonoids, among them the first biflavone methyl ether from a moss, and six derivatives of 4,2′-epoxy-3-phenylcoumarin — a group of isoflavone-related compounds — that has been found so far only in some seed plants. The structures of all compounds were elucidated and confirmed spectroscopically.
