Form and level of coumarin in deer’s tongue,Trilisa odoratissima

Fresh leaves of deer’s tongue contain large quantities (more than 10% of the dry weight, in some cases) of o-hydroxycinnamic acid (o-HCA). Bothcis- andtrans-o- HCA are present, and both isomers exist in the fresh tissue predominantly as glucosides. Cured deer’s tongue leaves contain relatively high levels of coumarin and lower amounts of o-HCA glucosides. It is probable that during the curing processcis-o-HCA glucoside is hydrolyzed by an endogenous ß-glucosidase, and that the liberated cis-o-HCA lactonizes spontaneously to form coumarin.
