In vitro shoot and root organogenesis, plant regeneration and production of tropane alkaloids in some species of Schizanthus

Ten alkaloids ranging from simple pyrrolidine derivatives to tropane esters derived from angelic, tiglic, senecioic or methylmesaconic acids were obtained from in vitro regenerated plantlets Schizanthus hookeri Gill. (Solanaceae), an endemic Chilean plant. One of them, 3α-methylmesaconyloxytropane, is hitherto unknown.
