The first isolation of lignans, megacerotonic acid and anthocerotonic acid, from non-vascular plants, Anthocerotae (Hornworts)
The new lignans, megacerotonic acid and anthocerotonic acid, were isolated from the Anthocerotae (Hornworts), Megaceros flagellaris and Anthoceros punctatus. Their structures were determined by spectroscopic mothods. This is the first known example of lignans isolated from non-vascular plants.
